Francis Crick
Professor Francis Harry Compton Crick, OM FRS (8 June 1916 - 28 July 2004) was a British physicist, molecular biologist and neuroscientist, most noted for being one of the co-discoverers of the structure of the DNA molecule in 1953. After the discovery of the double helix model of DNA, Crick’s interests quickly turned to the biological implications of the structure. Proof that the genetic code is a degenerate triplet code finally came from genetics experiments, some of which were performed by Crick. The details of the code came mostly from work by Marshall Nirenberg and others who synthesized synthetic RNA molecules and used them as templates for in vitro protein synthesis.
