Their work would lead t Werner Arber (2014) ... classify these mechanisms into three natural strategies of genetic variation according to specific qualities of their contributions to biological evolution: local DNA sequence changes, intragenomic rearrangements of DNA segments, and the acquisition of a segment of foreign DNA by horizontal gene transfer. Clever people use the servant with the scissors to find out the secrets of the kings. He was awarded the Nobel Prize for Physics in 1932 for his work on quantum mechanics. 18 Jan 2021. Werner Arber. Along with American researchers Hamilton Smith and Daniel Nathans, Werner Arber shared the 1978 Nobel Prize in Physiology or Medicine for the discovery of restriction endonucleases. Werner Arber (*1929) is a famous microbiologist and geneticist. Insight into Molecular Evolution - Practical and Philosophical Consequences. He won the Nobel Prize in Physiology or Medicine in 1978 for his discovery of restriction endonucleases which he shared with Daniel Nathans and Hamilton O. Smith . American microbiologist. When Werner Arber’s daughter Silvia heard of his discovery after he got the Nobel Prize she made a story out of the discovery which received wide publicity. He became one of the first few people who started work at the ‘Biozentrum’ which had been recently constructed to house the different departments of microbiology, biophysics, biochemistry, cell biology, pharmacology and structural biology. Restriction enzyme is an enzyme that … The second is rather political and it consists in actions to stimulate continued awareness of responsibility to work with a maximum of care in all scientific investigations, which should, however, be allowed to be done under optimal academic freedom. It soon also became obvious that restriction and modification were properties of the bacterial strains and acted not only on infecting bacteriophage DNA, but also on cellular DNA as manifested in conjugation experiments. He is very long, but skinny. Very rapidly I realized that this was due to host-controlled modification, a phenomenon described for lambda and E. coli strains seven years earlier by Joe Bertani and Jean Weigle. She did her PhD with Swiss scientist Werner Arber and in the process discovered restriction enzymes, proteins that can cut DNA at precise points. This autobiography/biography was written These are thick and short, almost like balls. On the recommendation of my professor in experimental physics, Paul Scherrer, I took an assistantship for electron microscopy at the Biophysics Laboratory at the University of Geneva in November 1953. This model, which was published in 1953, was incorrect, but it did lay the foundation for James Watson and Francis Crick's correct model of DNA as a double helix. This phenomenon became the topic of Daisy Dussoix’s doctoral thesis, who very carefully not only studied the DNA degradation of phage that was not properly modified, but who also tried to detect parallels between the fate of unmodified DNA in restrictive conditions and of irradiated DNA in normal host cells. D. student, and Dorothea Scandella, a postdoctoral fellow, explored two other mechanisms found in some E. coli strains or mutants and affecting more specifically than restriction and modification systems particular steps in the propagation of bacteriophage lambda. For us human beings these instructions of the king are a mystery. American microbiologist. In 1962 Arber presented the findings more elaborately to the ‘Science Faculty’ at the ‘University of Geneva’ for which he was awarded by the university. Although we had a few excellent students in our laboratories, the teaching of molecular genetics at the University of Geneva in the 1960’s suffered a bit from a lack of interest by the young generation. Shared the 1978 Nobel Prize in Physiology or Medicine with Werner Arber and Daniel Nathans for the discovery of restriction endonucleases, which led to the development of recombinant DNA technology. For the last several years I have turned my principal interests to the intriguing activities of insertion elements and transposons, which by their actions on genetic rearrangements, seem to be the main driving forces of evolution in microorganisms. In the summer of 1956, we learned about experiments made by Larry Morse and Esther and Joshua Lederberg on the lambda-mediated transduction (gene transfer from one bacterial strain to another by a bacteriophage serving as vector) of bacterial determinants for galactose fermentation. English: Werner Arber (born 3 June 1929 in Gränichen, Aargau) is a Swiss microbiologist and geneticist. Prof. em. He next joined the gymnasium at the ‘Kantonsschule Aarau’ from where he received a B-type maturity in 1949. Arber started to work with Joe Bertani on a ‘bacteriophage’ of the E. Coli virus which Bertani had isolated a few years earlier. In 1965 he was promoted to the post of ‘Extraordinary Professor for Molecular Genetics’ by the ‘University of Geneva’. The 1978 Nobel Prize in Physiology or Medicine was awarded jointly to Werner Arber, Dan Nathans and Hamilton Smith for the discovery of "restriction enzymes and their application to problems of molecular genetics." He then enrolled at the ‘Swiss Federal Institute of Technology’ located in Zurich under the ‘University of Geneva’ and studied physics and chemistry for his diploma in ‘Natural Sciences’ from 1949 to 1953. Solid notions on naturally occurring genetic exchange between organisms that are not directly related will also form a good basis for a scientific evaluation of conjectural risks of in vitro recombinant DNA research. These years were devoted to hard work to consolidate the preliminary data and the concepts resulting from them, and to extend the acquired notions, in particular with regard to the mechanisms of modification by nucleotide methylation, with regard to the genetic control of restriction and modification and with regard to the enzymology and molecular mechanisms of these reactions. I was also anxious to know how the restriction of phage growth and the adaptation of lambda to the new host strain worked. WERNER ARBER Summary Applications of scientific knowledge often refer to technological uses, but their impact on our world view can also be of great importance. On the other hand, I had remained in close contact with Eduard Kellenberger, and he urged me to come back to Geneva in order to lead an investigation on radiation effects on microorganisms. At the same time, Grete Kellenberger had looked at the fate of DNA from irradiated phage lambda upon infection of host bacteria: part of it was rapidly degraded after injection into the host. At the end of the 1950’s, a special credit had been voted for by the Swiss Parliament for research in atomic energy, including radiation effects on living organisms. The king is like a book, in which everything is noted on the work to be done by the servants. If a foreign king invades a bacterium, this servant can cut him in small fragments, but he does not do any harm to his own king. Luria had found that the viruses that infect bacteria known as ‘bacteriophages’ are themselves affected by hereditary mutations while inducing hereditary mutations in their hosts. Both of these kinds of applications have their cultural values. by the Laureate. In the story the DNA has been named as the King ruling over a kingdom of subjects who are the bacteria. This may be the reason why I received offers to spend additional postdoctoral time in several excellent laboratories. For this reason my father received the Nobel Prize for the discovery of the servant with the scissors”. any particular region of the host chromosome gets at some low frequency wrapped into P1 phage particles if P1 multiplies in a cell, and this enables the geneticists to carry out linkage studies of bacterial genes. From 1949 to 1953 I studied towards the diploma in Natural Sciences at the Swiss Polytechnical School in Zurich. These can be grouped into three strategies with different qualities with regard to their contributions to biological evolution. We could indeed show that lambda-mediated transduction is based on the formation of substitution mutants, which had replaced a part of the phage genes by genes from the bacterial chromosome. It is in the last year of this study that I made my first contacts with fundamental research, when working on the isolation and characterisation of a new isomer of Cl, The Nobel Prize in Physiology or Medicine 1978, Werner Arber - Nobel Lecture: Promotion and Limitation of Genetic Exchange. Werner Arber. Famous Foreign Biologists and their Significant Contributions. Born in: Gränichen, Aarau, Aargau, Switzerland, awards: 1978 Nobel Prize in Physiology or Medicine, See the events in life of Werner Arber in Chronological Order. Another significant contribution to the process of humulin production was by Werner Arber, Hamilton O. Smith, and Daniel Nathans in the late 1960s and early 1970s, as they were responsible for discovering the restriction enzymes. In the 1950’s the Biophysics Laboratory at the University of Geneva was lucky enough to receive each summer for several months the visit of Jean Weigle. Educated in the Swiss public school system, he entered the Federal Institute of Technology in … Shared the 1978 Nobel Prize in Physiology or Medicine with Werner Arber and Daniel Nathans for the discovery of restriction endonucleases, which led to the development of recombinant DNA technology. D. exam in the summer of 1958 I had the chance to receive an offer to work at the University of Southern California in Los Angeles with Joe Bertani, a former collaborator of Jean Weigle. He was the former professor of experimental physics at the University of Geneva. This web page shows only a small excerpt of our Arber research. These colonies remind me of a city with many inhabitants. Werner Arber (born 3 June 1929 in Gränichen, Aargau) is a Swiss microbiologist and geneticist. Werner Arber and Hamilton Smith both participated in the CSHL meeting. The opportunity made Arber give up his job involving electron microscopy and change over to research in genetics which became a passion with him over the years. These topics had already engaged the attention of Jean Weigle and Grete Kellenberger for a number of years. Because of their independence on extended nucleotide homologies these forces bring about exchange of largely unrelated genetic materials. With the resulting little pieces it is much easier to investigate the secrets. I was born on June 3rd, 1929 in Gränichen in the Canton of Aargau, Switzerland, where I went to the public schools until the age of 16. Additional contributions to this goal come from contacts with other nearby University Institutes as well as with the private research Institutions in the city. Phage P1 rapidly had become a very welcome tool of bacterial geneticists, since it gives general transduction, i.e. He received the 1980 Nobel Prize in Chemistry for his contribution to the field of recombinant DNA technology. He was also invited by Eduard Kellenberger to return to Geneva for research on the effect of radiation on micro-organisms. MLA style: Werner Arber – Biographical. He used his Nobel Prize money to invite his friends for this walk. In 1978, he won the Nobel price in medicines and physiology. My research interests focus on mechanisms to promote and to inhibit the exchange of genetic information between microorganisms: DNA restriction and modification systems; genetic recombination mechanisms, including transposition and site-specific inversion and their relevance for genetic rearrangements; and spontaneous mutagenesis and microbial evolution. After my Ph. Eduard Kellenberger felt that important contributions to the latter questions could be expected from studies with microorganisms, and he had therefore submitted a research proposal which found approval by the granting agency, the Swiss National Science Foundation. American microbiologist. Werner Arber Werner Arber was born on June 3, 1929, in Granichen, Switzerland. This allowed me to turn my main interests back to other mechanisms affecting either positively or negatively the exchange of genetic material. He also made other important contributions to science policy. In spite of spending many hours to keep the microscope “Arthur” in reasonable working condition, I had enough time not only to help developing preparation techniques for biological specimens in view of their observation in the electron microscope, but also to become familiar with fundamental questions of bacteriophage physiology and genetics, which at that time was still a relatively new and unknown field. He received many offers from various laboratories for post-doctoral work as his doctoral thesis was highly appreciated by the genetics fraternity. When I started investigations on the mechanisms of host-controlled modification, I did not of course imagine that this sidetrack would keep my interest for many years. For more than a century, these academic institutions have worked independently to select Nobel Laureates in each prize category. Werner Arber, Swiss microbiologist who was a corecipient of the 1978 Nobel Prize for Physiology or Medicine for his work in molecular genetics, specifically the discovery and application of enzymes that break the giant molecules of DNA into manageable pieces. Hamilton O. Smith, American microbiologist who shared, with Werner Arber and Daniel Nathans, the 1978 Nobel Prize for Physiology or Medicine for his discovery of a new class of restriction enzymes that recognize specific sequences of nucleotides in a molecule of DNA … Research Interests. Contributions to Science Arber studied the connection between the emergence and the development of botany following the natural history with plants’ evolution in terms of their descriptions, identifications, and classifications. These studies culminated in the final proof that modification in E. coli B and K is brought about by nucleotide methylation. Werner Arber's 170 research works with 7,182 citations and 10,774 reads, including: Genetic engineering represents a safe approach for innovations improving nutritional contents of major food crops He discovered restriction enzymes. Shared the 1978 Nobel Prize in Physiology or Medicine with Hamilton Smith and Daniel Nathans for the discovery of restriction endonucleases, which led to the development of recombinant DNA technology. It is virtually impossible to list them all in this context, but my warmest collective thanks go to all of them. In a more extended version I presented them in 1962 to the Science Faculty of the University of Geneva as my work of habilitation as privatdocent. Daisy Roulland-Dussoix was a Swiss microbial geneticist. I started my new appointment at the University of Basel in October 1971 after having spent one year as a visiting Miller Research Professor at the Department of Molecular Biology of the University of California in Berkeley. We have in vain spent much time in search for such evolutionary changes both after mutagenization and after recombination between two members of the same family of the above mentioned systems. He did many researches on the bacterial restrictions’ systems and movable genetic elements, the modification and restriction of the ribonucleic acid. Werner Arber, Daniel Nathans, and Hamilton Smith were awarded the Nobel Prize in Medicine/Physiology in 1978. He received his PhD from the ‘University of Geneva’ in 1958 in which his thesis was on the characteristics of ‘bacteriophage’. He received an offer from the ‘University of Southern California’ in Los Angeles in the summer of 1958 after completing his PhD to work with Joe Bertani who had collaborated earlier with Jean Weigle in the research on ‘bacteriophages’. Werner Arber is a Swiss microbiologist and geneticist who together with Daisy Dussoix helped discover and understand the mechanism of restriction enzymes, laying the foundation for their adoption as molecular scissors. But general knowledge on this to my mind extremely important field is still very scarce and deserves continued attention. Our postdoctoral workers Katsutoshi Mise, Shigeru Iida and Jürg Meyer brought important contributions to the understanding of these phenomena, mainly by the use of the bacteriophage P1 genome as a natural vector of transposable elements.

He received an offer from the ‘University of Southern California’ in Los Angeles in the summer of 1958 after completing his PhD to work with Joe Bertani who had collaborated earlier with Jean Weigle in the research on ‘bacteriophages’. Werner Arber is a Swiss microbiologist and geneticist who together with Daisy Dussoix helped discover and understand the mechanism of restriction enzymes, laying the foundation for their adoption as molecular scissors. But general knowledge on this to my mind extremely important field is still very scarce and deserves continued attention. Our postdoctoral workers Katsutoshi Mise, Shigeru Iida and Jürg Meyer brought important contributions to the understanding of these phenomena, mainly by the use of the bacteriophage P1 genome as a natural vector of transposable elements.

werner arber contributions

Learn more about Arber’s life and work. This was the end of my career as an electron microscopist and in chosing genetic and physiological approaches I became a molecular geneticist. I consider our insights into the natural laws of biological evolution as one of my contributions … This work would not have been possible without a very fruitful help by a large number of collaborators in my own laboratory and of colleagues working on related topics in their own laboratories. As an illustration that my work has not always been easy and accompanied by success, I would like to refer to my long, fruitless and thus largely unpublished attempts to find experimental evidence for the diversification of restriction and modification systems in the course of evolution. However, a lucky coincidence rapidly dissipated these concerns. at the time of the award and later published in the book series Les The enzymes are servants who use scissors to cut a foreign king entering the kingdom into pieces to learn his secrets without harming their own king. This laboratory was animated by Eduard Kellenberger and it had two prototype electron microscopes requiring much attention. He shared the prize with two other American scientists named Daniel Nathans and Hamilton Othanel Smith who collaborated with him in the experiments. The Nobel Prize in Physiology or Medicine 1978 was awarded jointly to Werner Arber, Daniel Nathans and Hamilton O. Smith "for the discovery of restriction enzymes and their application to problems of molecular genetics". In Basel, I was one of the first persons to work in the newly constructed Biozentrum, which houses several University Departments, in particular those of Biophysics, Biochemistry, Microbiology, Structural Biology, Cell Biology and Pharmacology. In 1953 he started his postgraduate work as an electron microscopist at the Biophysics Laboratory of the University of Geneva, mainly working with microorganisms. This concept had found its first experimental evidence during my two months’ visit in 1963 with Gunther Stent at the University of California in Berkeley. Their experiments also brought important conclusions with regard to the concept of the sites of recognition on the DNA for the restriction and modification enzymes. Werner Arber (born 3 June 1929) is a Swiss microbiologist and geneticist. Werner Arber's 170 research works with 7,182 citations and 10,774 reads, including: Genetic engineering represents a safe approach for innovations improving nutritional contents of major food crops 95, 166- 172, 1976) who encountered such a new system in their work with Salmonella recombinants. Educated in the Swiss public school system, he entered the Federal Institute of Technology in … Werner Arber and some more scientists had already started work on the findings of another Nobel laureate named Salvador Luria during the late 1950s and early 1960s. The Nobel Prizes 1978, Editor Wilhelm Odelberg, [Nobel Foundation], Stockholm, 1979. Restriction enzyme is an enzyme that … Very rapidly, thanks to the stimulating help by Jean Weigle and Grete Kellenberger, this turned out to be extremely fruitful. That the basic idea for this search was good was recently shown by Len Bullas, Charles Colson and Aline van Pel (J. Gen. Microbiol. ... Werner Arber. Werner Arber started this field of research in Geneva during the 1960’s. Werner Arber was born in Gränichen, Switzerland, on June 3, 1929. Werner Arber was awarded the Nobel Prize in Physiology or Medicine in 1978. Twelve laureates were awarded a Nobel Prize in 2020, for achievements that have conferred the greatest benefit to humankind. In his broad, interdisciplinary undergraduate education in natural sciences at the ETH Zürich, Werner Arber majored in experimental physics. Systems EcoK and EcoB form a closely related family as judged from genetic and functional studies. Several years later Urs Kühnlein, a Ph. Weigle had become a biologist doing research on ‘bacteriophage lamda’ while studying at the ‘Department of Biology’ under the ‘California Institute of Technology, Pasadena’. I then entered the gymnasium at the Kantonsschule Aarau where I got a B-type maturity in 1949. In 1953, he took an assistant-ship for electron microscopy at the Biophysical Laboratory at the University of Geneva. Nobel laureate Prof. Werner Arber visited Amity University and delivered an informative lecture outlining his sojourn into the mysteries of fundamental research which started 60 years ago. It was already known that bacteria could break down viruses called phages. Several years before, Bertani had isolated and characterised another bacteriophage of E. coli, P1. Discover Your Abilities and Aspirations! Werner Arber Werner Arber was born on June 3, 1929, in Granichen, Switzerland. From 1949 to 1953 I studied towards the diploma in Natural Sciences at the Swiss Polytechnical School in Zurich. I was extremely lucky to receive in my laboratory in the basement of the Physics Institute of the University of Geneva a number of first class graduate students, postdoctoral fellows and senior scientists. And so was the DNA from unirradiated phage lambda used to measure adsorption and DNA injection into restrictive bacterial strains! These plates contain colonies of bacteria. In 1963 he spent one year at the ‘Department of Molecular Biology’ under the ‘University of California, Berkeley’ as a visiting ‘Miller Research Professor’. Werner Arber (born 3 June 1929 in Gränichen, Aargau) is a Swiss microbiologist and geneticist. It might thus be justified to finish this curriculum vitae by its reproduction: When I come to the laboratory of my father, I usually see some plates lying on the tables. Werner Arber Biozentrum, University of Basel, Klingelbergstrasse 50-70, CH-4056 Basel, Switzerland By comparing strategies of genetic alterations introduced in genetic engineering with spontaneously occurring genetic variation, we have come to conclude that both processes depend on several distinct and specific molecular mechanisms. Not that I have lost my interest in them. He joined the ‘University of Basel’ in 1971 and worked there as a professor of microbiology up to 1996. (Dan Nathans passed away in 1999.) He was also inspired by the lectures given by Jean Weigle who had been a professor of experimental physics at the ‘University of Geneva’. To do so, they collect many servants with scissors and put them onto a king, so that the king is cut into pieces. In November 1953 he took up the job of an assistant for electron microscopy at the ‘Biophysics Laboratory’ at the ‘University of Geneva’. It is in the last year of this study that I made my first contacts with fundamental research, when working on the isolation and characterisation of a new isomer of Cl34, with a halflife of 1.5 seconds. He helped to keep the two electron microscopes in good working condition and spent a lot of time helping in the preparation of biological specimens to be viewed with the microscopes. For the last several years he has been involved in the study of ‘transposons’ and ‘insertion elements’ and their activities in providing the driving force required for the evolution of micro-organisms. These, at that time perhaps more subconscious concerns, might have helped me to accept in 1968 an offer for a professorship at the University of Basel, since I felt that more general interest would be given to molecular genetics in this city with a long tradition of biomedical research at its industries. After returning to Geneva he started working on the bacteriophage of E.Coli. Prix Nobel/ Nobel Lectures/The Nobel Prizes. University of Southern California, private coeducational institution of higher education in Los Angeles, California. In response to their interest and understanding for my scientific activities, I have tried to give them my personal affection needed for a harmonious life. Dr. Werner Arber is a pioneer in molecular biological research, investigating the structure and function of DNA and the interaction of genes and proteins. ... Werner Arber. Apart from this, he was also awarded the National Medal of Science in 1983. Greek philosopher and early scientist. During the last part of his studies he first became interested in fundamental research while trying to isolate an isomer and study its characteristics. Since these investigators had encountered defective lysogenic strains among their transductants, we felt that such strains should be included in the collection of lambda prophage mutants under study in our laboratory. It was already known that bacteria could break down viruses called phages. Werner Arber was born in Gränichen, Switzerland, on June 3, 1929. However, the strains thus obtained still did not allow an efficient propagation of lambda. Nobel Media AB 2021. He discovered restriction enzymes. In 1961 Arber and another geneticist, Daisy Dussoix, reported this phenomenon to the scientific community for the first time during the ‘First International Biophysics Congress’ which was held in Stockholm. I then entered the gymnasium at the Kantonsschule Aarau where I got a B-type maturity in 1949. In fact, one of the at first sight rather frustrating observation was that lysates of lambda-gal, which indeed could still cause the infected host cell to lyse as does wild type phage lambda, did not contain any structural components of lambda (phage particles, heads or tails) discernible in the electron microscope. Their work would lead to the development of recombinant DNA technology. In 1968 he received an offer of professorship at the ‘University of Basel’. I see two ways to reach this goal. This was when direct financial help was not available from the Swiss federal government. This diversity within the same house largely contributes to fruitful collaborative projects and it helps to keep horizons broad both in research and teaching. He studied at the public schools in Granichen until he was 16. While doing this he became familiar with the basic issues related to genetics and the physiology of ‘bacteriophages’. In 1981 he became a member of the ‘World Knowledge Dialogue Scientific Board’ and also a member of the ‘Pontifical Academy of Sciences’. As a compromise, I decided to return to Geneva at the beginning of 1960, but only after having spent several very fruitful weeks at each of the laboratories of Gunther Stent in Berkeley, Joshua Lederberg in Stanford and Salvador Luria at the Massachusetts Institute of Technology, Cambridge. I was lucky to benefit from such a support form 1965 to 1970. Before returning to Geneva at the beginning of 1960, he spent a few weeks working at the ‘Gunther Stent’ laboratory in Berkeley, the ‘Joshua Lederberg’ laboratory in Stanford and the ‘Salvador Luria’ laboratory at the ‘Massachusetts Institute of Technology’ in Cambridge. Read more >> Aristotle (384-322 B.C.). Their work would lead t Werner Arber (2014) ... classify these mechanisms into three natural strategies of genetic variation according to specific qualities of their contributions to biological evolution: local DNA sequence changes, intragenomic rearrangements of DNA segments, and the acquisition of a segment of foreign DNA by horizontal gene transfer. Clever people use the servant with the scissors to find out the secrets of the kings. He was awarded the Nobel Prize for Physics in 1932 for his work on quantum mechanics. 18 Jan 2021. Werner Arber. Along with American researchers Hamilton Smith and Daniel Nathans, Werner Arber shared the 1978 Nobel Prize in Physiology or Medicine for the discovery of restriction endonucleases. Werner Arber (*1929) is a famous microbiologist and geneticist. Insight into Molecular Evolution - Practical and Philosophical Consequences. He won the Nobel Prize in Physiology or Medicine in 1978 for his discovery of restriction endonucleases which he shared with Daniel Nathans and Hamilton O. Smith . American microbiologist. When Werner Arber’s daughter Silvia heard of his discovery after he got the Nobel Prize she made a story out of the discovery which received wide publicity. He became one of the first few people who started work at the ‘Biozentrum’ which had been recently constructed to house the different departments of microbiology, biophysics, biochemistry, cell biology, pharmacology and structural biology. Restriction enzyme is an enzyme that … The second is rather political and it consists in actions to stimulate continued awareness of responsibility to work with a maximum of care in all scientific investigations, which should, however, be allowed to be done under optimal academic freedom. It soon also became obvious that restriction and modification were properties of the bacterial strains and acted not only on infecting bacteriophage DNA, but also on cellular DNA as manifested in conjugation experiments. He is very long, but skinny. Very rapidly I realized that this was due to host-controlled modification, a phenomenon described for lambda and E. coli strains seven years earlier by Joe Bertani and Jean Weigle. She did her PhD with Swiss scientist Werner Arber and in the process discovered restriction enzymes, proteins that can cut DNA at precise points. This autobiography/biography was written These are thick and short, almost like balls. On the recommendation of my professor in experimental physics, Paul Scherrer, I took an assistantship for electron microscopy at the Biophysics Laboratory at the University of Geneva in November 1953. This model, which was published in 1953, was incorrect, but it did lay the foundation for James Watson and Francis Crick's correct model of DNA as a double helix. This phenomenon became the topic of Daisy Dussoix’s doctoral thesis, who very carefully not only studied the DNA degradation of phage that was not properly modified, but who also tried to detect parallels between the fate of unmodified DNA in restrictive conditions and of irradiated DNA in normal host cells. D. student, and Dorothea Scandella, a postdoctoral fellow, explored two other mechanisms found in some E. coli strains or mutants and affecting more specifically than restriction and modification systems particular steps in the propagation of bacteriophage lambda. For us human beings these instructions of the king are a mystery. American microbiologist. In 1962 Arber presented the findings more elaborately to the ‘Science Faculty’ at the ‘University of Geneva’ for which he was awarded by the university. Although we had a few excellent students in our laboratories, the teaching of molecular genetics at the University of Geneva in the 1960’s suffered a bit from a lack of interest by the young generation. Shared the 1978 Nobel Prize in Physiology or Medicine with Werner Arber and Daniel Nathans for the discovery of restriction endonucleases, which led to the development of recombinant DNA technology. For the last several years I have turned my principal interests to the intriguing activities of insertion elements and transposons, which by their actions on genetic rearrangements, seem to be the main driving forces of evolution in microorganisms. In the summer of 1956, we learned about experiments made by Larry Morse and Esther and Joshua Lederberg on the lambda-mediated transduction (gene transfer from one bacterial strain to another by a bacteriophage serving as vector) of bacterial determinants for galactose fermentation. English: Werner Arber (born 3 June 1929 in Gränichen, Aargau) is a Swiss microbiologist and geneticist. Prof. em. He next joined the gymnasium at the ‘Kantonsschule Aarau’ from where he received a B-type maturity in 1949. Arber started to work with Joe Bertani on a ‘bacteriophage’ of the E. Coli virus which Bertani had isolated a few years earlier. In 1965 he was promoted to the post of ‘Extraordinary Professor for Molecular Genetics’ by the ‘University of Geneva’. The 1978 Nobel Prize in Physiology or Medicine was awarded jointly to Werner Arber, Dan Nathans and Hamilton Smith for the discovery of "restriction enzymes and their application to problems of molecular genetics." He then enrolled at the ‘Swiss Federal Institute of Technology’ located in Zurich under the ‘University of Geneva’ and studied physics and chemistry for his diploma in ‘Natural Sciences’ from 1949 to 1953. Solid notions on naturally occurring genetic exchange between organisms that are not directly related will also form a good basis for a scientific evaluation of conjectural risks of in vitro recombinant DNA research. These years were devoted to hard work to consolidate the preliminary data and the concepts resulting from them, and to extend the acquired notions, in particular with regard to the mechanisms of modification by nucleotide methylation, with regard to the genetic control of restriction and modification and with regard to the enzymology and molecular mechanisms of these reactions. I was also anxious to know how the restriction of phage growth and the adaptation of lambda to the new host strain worked. WERNER ARBER Summary Applications of scientific knowledge often refer to technological uses, but their impact on our world view can also be of great importance. On the other hand, I had remained in close contact with Eduard Kellenberger, and he urged me to come back to Geneva in order to lead an investigation on radiation effects on microorganisms. At the same time, Grete Kellenberger had looked at the fate of DNA from irradiated phage lambda upon infection of host bacteria: part of it was rapidly degraded after injection into the host. At the end of the 1950’s, a special credit had been voted for by the Swiss Parliament for research in atomic energy, including radiation effects on living organisms. The king is like a book, in which everything is noted on the work to be done by the servants. If a foreign king invades a bacterium, this servant can cut him in small fragments, but he does not do any harm to his own king. Luria had found that the viruses that infect bacteria known as ‘bacteriophages’ are themselves affected by hereditary mutations while inducing hereditary mutations in their hosts. Both of these kinds of applications have their cultural values. by the Laureate. In the story the DNA has been named as the King ruling over a kingdom of subjects who are the bacteria. This may be the reason why I received offers to spend additional postdoctoral time in several excellent laboratories. For this reason my father received the Nobel Prize for the discovery of the servant with the scissors”. any particular region of the host chromosome gets at some low frequency wrapped into P1 phage particles if P1 multiplies in a cell, and this enables the geneticists to carry out linkage studies of bacterial genes. From 1949 to 1953 I studied towards the diploma in Natural Sciences at the Swiss Polytechnical School in Zurich. These can be grouped into three strategies with different qualities with regard to their contributions to biological evolution. We could indeed show that lambda-mediated transduction is based on the formation of substitution mutants, which had replaced a part of the phage genes by genes from the bacterial chromosome. It is in the last year of this study that I made my first contacts with fundamental research, when working on the isolation and characterisation of a new isomer of Cl, The Nobel Prize in Physiology or Medicine 1978, Werner Arber - Nobel Lecture: Promotion and Limitation of Genetic Exchange. Werner Arber. Famous Foreign Biologists and their Significant Contributions. Born in: Gränichen, Aarau, Aargau, Switzerland, awards: 1978 Nobel Prize in Physiology or Medicine, See the events in life of Werner Arber in Chronological Order. Another significant contribution to the process of humulin production was by Werner Arber, Hamilton O. Smith, and Daniel Nathans in the late 1960s and early 1970s, as they were responsible for discovering the restriction enzymes. In the 1950’s the Biophysics Laboratory at the University of Geneva was lucky enough to receive each summer for several months the visit of Jean Weigle. Educated in the Swiss public school system, he entered the Federal Institute of Technology in … Shared the 1978 Nobel Prize in Physiology or Medicine with Werner Arber and Daniel Nathans for the discovery of restriction endonucleases, which led to the development of recombinant DNA technology. D. exam in the summer of 1958 I had the chance to receive an offer to work at the University of Southern California in Los Angeles with Joe Bertani, a former collaborator of Jean Weigle. He was the former professor of experimental physics at the University of Geneva. This web page shows only a small excerpt of our Arber research. These colonies remind me of a city with many inhabitants. Werner Arber (born 3 June 1929 in Gränichen, Aargau) is a Swiss microbiologist and geneticist. Werner Arber and Hamilton Smith both participated in the CSHL meeting. The opportunity made Arber give up his job involving electron microscopy and change over to research in genetics which became a passion with him over the years. These topics had already engaged the attention of Jean Weigle and Grete Kellenberger for a number of years. Because of their independence on extended nucleotide homologies these forces bring about exchange of largely unrelated genetic materials. With the resulting little pieces it is much easier to investigate the secrets. I was born on June 3rd, 1929 in Gränichen in the Canton of Aargau, Switzerland, where I went to the public schools until the age of 16. Additional contributions to this goal come from contacts with other nearby University Institutes as well as with the private research Institutions in the city. Phage P1 rapidly had become a very welcome tool of bacterial geneticists, since it gives general transduction, i.e. He received the 1980 Nobel Prize in Chemistry for his contribution to the field of recombinant DNA technology. He was also invited by Eduard Kellenberger to return to Geneva for research on the effect of radiation on micro-organisms. MLA style: Werner Arber – Biographical. He used his Nobel Prize money to invite his friends for this walk. In 1978, he won the Nobel price in medicines and physiology. My research interests focus on mechanisms to promote and to inhibit the exchange of genetic information between microorganisms: DNA restriction and modification systems; genetic recombination mechanisms, including transposition and site-specific inversion and their relevance for genetic rearrangements; and spontaneous mutagenesis and microbial evolution. After my Ph. Eduard Kellenberger felt that important contributions to the latter questions could be expected from studies with microorganisms, and he had therefore submitted a research proposal which found approval by the granting agency, the Swiss National Science Foundation. American microbiologist. Werner Arber Werner Arber was born on June 3, 1929, in Granichen, Switzerland. This allowed me to turn my main interests back to other mechanisms affecting either positively or negatively the exchange of genetic material. He also made other important contributions to science policy. In spite of spending many hours to keep the microscope “Arthur” in reasonable working condition, I had enough time not only to help developing preparation techniques for biological specimens in view of their observation in the electron microscope, but also to become familiar with fundamental questions of bacteriophage physiology and genetics, which at that time was still a relatively new and unknown field. He received many offers from various laboratories for post-doctoral work as his doctoral thesis was highly appreciated by the genetics fraternity. When I started investigations on the mechanisms of host-controlled modification, I did not of course imagine that this sidetrack would keep my interest for many years. For more than a century, these academic institutions have worked independently to select Nobel Laureates in each prize category. Werner Arber, Swiss microbiologist who was a corecipient of the 1978 Nobel Prize for Physiology or Medicine for his work in molecular genetics, specifically the discovery and application of enzymes that break the giant molecules of DNA into manageable pieces. Hamilton O. Smith, American microbiologist who shared, with Werner Arber and Daniel Nathans, the 1978 Nobel Prize for Physiology or Medicine for his discovery of a new class of restriction enzymes that recognize specific sequences of nucleotides in a molecule of DNA … Research Interests. Contributions to Science Arber studied the connection between the emergence and the development of botany following the natural history with plants’ evolution in terms of their descriptions, identifications, and classifications. These studies culminated in the final proof that modification in E. coli B and K is brought about by nucleotide methylation. Werner Arber's 170 research works with 7,182 citations and 10,774 reads, including: Genetic engineering represents a safe approach for innovations improving nutritional contents of major food crops He discovered restriction enzymes. Shared the 1978 Nobel Prize in Physiology or Medicine with Hamilton Smith and Daniel Nathans for the discovery of restriction endonucleases, which led to the development of recombinant DNA technology. It is virtually impossible to list them all in this context, but my warmest collective thanks go to all of them. In a more extended version I presented them in 1962 to the Science Faculty of the University of Geneva as my work of habilitation as privatdocent. Daisy Roulland-Dussoix was a Swiss microbial geneticist. I started my new appointment at the University of Basel in October 1971 after having spent one year as a visiting Miller Research Professor at the Department of Molecular Biology of the University of California in Berkeley. We have in vain spent much time in search for such evolutionary changes both after mutagenization and after recombination between two members of the same family of the above mentioned systems. He did many researches on the bacterial restrictions’ systems and movable genetic elements, the modification and restriction of the ribonucleic acid. Werner Arber, Daniel Nathans, and Hamilton Smith were awarded the Nobel Prize in Medicine/Physiology in 1978. He received his PhD from the ‘University of Geneva’ in 1958 in which his thesis was on the characteristics of ‘bacteriophage’. He received an offer from the ‘University of Southern California’ in Los Angeles in the summer of 1958 after completing his PhD to work with Joe Bertani who had collaborated earlier with Jean Weigle in the research on ‘bacteriophages’. Werner Arber is a Swiss microbiologist and geneticist who together with Daisy Dussoix helped discover and understand the mechanism of restriction enzymes, laying the foundation for their adoption as molecular scissors. But general knowledge on this to my mind extremely important field is still very scarce and deserves continued attention. Our postdoctoral workers Katsutoshi Mise, Shigeru Iida and Jürg Meyer brought important contributions to the understanding of these phenomena, mainly by the use of the bacteriophage P1 genome as a natural vector of transposable elements.
