Watson Wat·son (wŏt'sən), James Dewey. Born 1928.
American biologist who with Francis Crick proposed a spiral model, the double helix, for the molecular structure of DNA. He shared a 1962 Nobel Prize for advances in the study of genetics.
|Watson (wŏt'sən) Pronunciation Key
American biologist who, working with Francis Crick, identified the structure of DNA in 1953. By analyzing the patterns cast by x-rays striking DNA molecules, they discovered that DNA has the structure of a double helix, two spirals linked together by bases in ladderlike rungs. For this work Watson and Crick shared with Maurice Wilkins the 1962 Nobel Prize for physiology or medicine.
