Crick, Francis Harry Compton
English molecular biologist who was awarded a Nobel Prize for Physiology or Medicine in 1962, together with Maurice Wilkins and James Watson, for the discovery of the double-helical structure of DNA and of the significance of this structure in the replication and transfer of genetic information.
Using Wilkins's and others' discoveries, Crick and Watson postulated that DNA consists of a double helix consisting of two parallel chains of alternate sugar and phosphate groups linked by pairs of organic bases. They built molecular models which also explained how genetic information could be coded – in the sequence of organic bases. Crick and Watson published their work on the proposed structure of DNA in 1953. Their model is now generally accepted as correct.
