born June 8, 1916, Northampton, Northamptonshire, Eng.
British biophysicist.
Educated at University College, London, he helped develop magnetic mines for naval use during World War II but returned to biology after the war. He worked at Cambridge University with Maurice Wilkins to construct a molecular model of DNA consistent with its known physical and chemical properties, work for which the three shared a 1962 Nobel Prize. Crick also discovered that each group of three bases (a codon) on a single DNA strand designates the position of a specific amino acid on the backbone of a protein molecule, and he helped determine which codons code for each amino acid normally found in protein, thus clarifying the way the cell uses DNA to build proteins.
