James Dewey Watson was born in Chicago, Ill., on April 6, 1928. He attended Horace Mann Grammar School and then South Shore High School. At the age of 15, he transferred to the University of Chicago in an experimental scholarship program for gifted youngsters. A lifelong interest in birds led him to study biology, and he was awarded his Bachelor of...
Watson and Crick decided to use a model-building approach to try to discern the molecular structure of the DNA molecule. Both were convinced that understanding the molecular geometry would be central to discovering how DNA could transmit genetic information from parent to daughter cells. The men understood that discovering the structure of the DNA ...
Watson and Crick used the new information to construct a new double-stranded helix model with the nitrogen bases paired A to T and C to G in the center. This base pairing immediately suggested to Crick that one side of the molecule could serve as a template to exactly replicate DNA sequences to pass on genetic information during cell reproduction. ...
In 1968, Watson became the director of the Cold Spring Harbor Laboratory. At the time, the institution was struggling financially, but Watson proved to be very good at raising funds for research. Under Watson’s leadership, Cold Spring became one of the world’s leading institutions for research in molecular biology. In 1990, Watson was named head of...

The discovery in 1953 of the double helix, the twisted-ladder structure of deoxyribonucleic acid (DNA), by James Watson and Francis Crick marked a milestone in the history of science and gave rise to modern molecular biology, which is largely concerned with understanding how genes control the chemical processes within cells.
Apr 2, 2014 · James D. Watson is credited with the discovery of the double-helix structure of DNA along with Francis Crick. Watson received a 1962 Nobel Prize and went on to do work in cancer...
