Arthur Kornberg

Born 3 Mar 1918; died 26 Oct 2007 at age 89.American biochemist and physician who shared the 1959 Nobel Prize for Physiology or Medicine (with Severo Ochoa) for the “discovery of the mechanisms in the biological synthesis of deoxyribonucleic acid” Kornberg showed not only how DNA molecules are duplicated both in nature within bacterial cells, but also isolated the first DNA polymerising enzyme (1958), and reproduced the process in the test tube. His research included studying the nucleic acids which control heredity in animals, plants, bacteria and viruses.«
