Extractions: ARBER Werner (Gränichen (Svizzera), 1929). Microbiologia Dopo la laurea in Medicina (1953), lavora al Dipartimento di Microbiologia dell'Università di Los Angeles e a Berkeley (University of California); diviene professore di Microbiologia all'Università di Basilea. Ad Arber si deve la scoperta degli "enzimi di restrizione", considerati come "coltelli chimici" per i quali i geni (DNA) vengono scissi in frammenti ben definiti: egli ammette l'esistenza di enzimi di restrizione, che scindono il DNA, e enzimi di modificazione, che inibiscono tale restrizione. Questi enzimi agiscono in siti specifici delle molecole del DNA, scindendo la molecola (restrizione) oppure mutilandola (modificazione). Per questa scoperta Arber riceve il premio Nobel 1978 per la fisiologia e la medicina, insieme con Nathans e Smith

Extractions: 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 laboratory was animated by Eduard Kellenberger and it had two prototype electron microscopes requiring much attention. 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. My first contribution to our journal club concerned Watson and Crick's papers on the structure of DNA. 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. He was the former professor of experimental physics at the University of Geneva. After having suffered a heart attack, he had left Geneva to become a researcher at the Department of Biology of the California Institute of Technology in Pasadena. There, he had been converted to a biologist under the influence of and had chosen to study bacteriophage lambda. This is why the first electron micrographs of phage lambda were made in Geneva. Stimulated by Jean Weigle we soon turned our interests also to other properties of lambda, and the study of defective lambda prophage mutants became the topic of my doctoral thesis.

Extractions: Symposium in Honour of the 75th Anniversary of Werner Arber In 1978, Werner Arber, at that time a Full Professor in Microbiology at the Biozentrum of the University of Basel, was awarded the Nobel Prize in Physiology or Medicine "for the discovery of restriction enzymes and their application to problems of molecular genetics", together with Daniel Nathans and Hamilton O. Smith. In 2004 now, Werner Arber is celebrating his 75th birthday, and the Biozentrum will hold a symposium in his honour. It will take place on Friday July 9, 2004 in Basel. Also present will be his co-laureate Hamilton O. Smith, giving a talk about "defining a minimal genome", as well as Richard J. Roberts, one of the two Nobel Prize Laureates of 1993 in Physiology or Medicine, honoured for "their discoveries of split genes", giving a talk about "the genomics of restriction and modification".

Extractions: Daniel Nathans and Hamilton Othanel Smith of the United States of the Nobel Prize for Physiology or Medicine for 1978. All three were cited for their work in molecular genetics, specifically the discovery and application of enzymes that break the giant molecules of deoxyribonucleic acid (DNA) into manageable pieces, small enough to be separated for individual study but large enough to retain bits of the genetic information inherent in the sequence of units that make up the original substance. During the late 1950s and early '60s Arber and several others extended the work of an earlier Nobel laureate, Salvador Luria , who had observed that bacteriophages (viruses that infect bacteria) not only induce hereditary mutations in their bacterial hosts but at the same time undergo hereditary mutations themselves. Arber's research was concentrated on the action of protective enzymes present in the bacteria, which modify the DNA of the infecting virus e.g., the restriction enzyme, so-called for its ability to restrict the growth of the bacteriophage by cutting the molecule of its DNA to pieces.

Extractions: Swiss microbiologist who studied Luria's discovery that bacteriophages not only induce mutations in the cells they infect, but also undergo mutations themselves. Arber showed that bacterial cells could defend themselves from bacteriophages with restriction enzymes . Arber showed a particular enzyme only splits DNA molecules with a given sequence of nucleotides . This phenomenon was extended by Nathans and Hamilton Smith , leading to the recombinant DNA techniques of Berg Nathans Hamilton Smith , and Arber shared the 1978 Nobel Prize in medicine for their work.

Extractions: Arber, Werner I was born on June 3rd, 1929 in Gronichen in the Canton of Aargau, Switzerland, where I went to the public schools until the age of 16. I then entered the gymnasium at the Kantonsschule Aarau where I got a B-type maturity in 1949. From 1949 to 1953 I studied towards the diploma in Natural Sciences at the Swiss Polytechnical School in Zurich. 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. 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.
