History of Recombinant DNA1972 - The idea for recombinant DNA was first proposed by PeterLobban, a graduate student at Stanford University Medical School.1972 -73 - The first publications describing the successful production andintracellular replication of recombinant DNA appeared.1974 – Patent on recombinant DNA was awarded in 1980.1982 - The first licensed drug generated using recombinant DNAtechnology was human insulin, developed by Genentech and Licensed byEli Lilly and Company. http://en.wikipedia.org/wiki/Recombinant_DN A#History_of_recombinant_DNA
