  1. Lecture 05: The Founders of Genetic Engineering

  2. 1. Professor Paul Berg  DNA + SV40 → Recombination DNA

  3. Brief CV • Paul Berg witnessed first-hand the history of recombinant DNA research and regulation, having been in the forefront of both movements since he was a young man. • He became a Professor of Biochemistry at Stanford University School of Medicine in 1959, when he was 33. • He was elected to be the National Academy of Sciences before he was 40, and he gained early recognition and influence when he delineated the key steps in which DNA produces proteins. • Berg was awarded the Nobel Prize for Chemistry in 1980 for his work with DNA.

  13. F. Sanger received two Nobel prizes

  14. Frederick Sanger The Nobel Prize in Chemistry 1958 and 1980 Autobiography I was born on 13th August 1918 in the village of Rendcombe in Gloucestershire, where my father, also Frederick Sanger, was a medical practitioner. Influenced by him, I soon became interested in biology and developed a respect for the importance of science and the scientific method. At Bryanston School and St John's College, Cambridge, I was probably above average but not an outstanding scholar. Initially I had intended to study medicine, but before going to University I had decided that I would be better suited to a career in which I could concentrate my activities and interests more on a single goal than appeared to be possible in my father's profession. So I decided to study science and, on arrival at Cambridge .

  15. Beautiful Family Life Autobiography I was married to Margaret Joan Howe in 1940. Although not a scientist herself she has contributed more to my work than anyone else by providing a peaceful and happy home. We have two sons, Robin and Peter, born in 1943 and 1946, and a daughter, Sally Joan, born in 1960. Apart from my work my main interests are gardening and what can best be described as “messing about in boats”.

  16. Since 1943 his work has been concerned largely with problems related to the determination of the structure of proteins. These studies resulted in the determination of the structure of insulin. • From 1944 to 1951 he held a Beit Memorial Fellowship for Medical Research and since 1951 he has been a member of the External Staff of the Medical Research Council. His present position is Head of the Division of Protein Chemistry in M.R.C. Laboratory for Molecular Biology at Cambridge. Frederick Sanger received his first Nobel Prize in Chemistry in 1958

  17. Nobel Lecture, December 11, 1958

  18. In 1962 I moved to their newly built Laboratory of Molecular Biology in Cambridge, together with F.H.C. Crick, J.C. Kendrew, H.E. Huxley and A. Klug. In this atmosphere I soon became interested in nucleic acids. My work on nucleic acids is summarized in my Nobel lecture. This work has not been done single-handed and it owes much to the excellent collaborators I have had. Most of these have been students and postdoctoral fellows spending a few years in the laboratory and bringing their experience and ideas with them, but I feel particularly indebted to my more permanent colleagues, B.G. Barrell, A.R. Coulson and G.G. Brownlee, who have contributed so much to the methods we have developed.

  19. Didesoxy DNA sequencing • The chemical method of DNA sequencing hat largely been superseded by the method of F. Sanger, which uses ddNTP to terminate enzymiclly synthesized copies of template (Fig. I). A sequencing primer is annealed to a dsDNA template molecule and a DNA polymerase extends the primer using ddNTPs. • The extension reaction is split into four specific ddNTPs and separately with one of the four specific ddNTPs, and S four samples (usually radioactive) are analyzed by PAGE.

  20. DETERMINATION OF NUCLEOTIDESEQUENCES IN DNANobel lecture, 8 December 1980

  21. The term "shotgun" to denote sequencing of a large number of random DNA clones was first coined by F. Sanger and co-workers in 1982.
