Chemical structure of DNA discovered
On February 28, 1953, Cambridge University scientists James D. Watson and Francis H.C. Crick announce that they have determined the double-helix structure of DNA, the molecule containing human genes. The molecular biologists were aided significantly by the work of another DNA researcher, Rosalind Franklin, although she is not included in the announcement, nor did she share the subsequent Nobel Prize award for it.
Though DNA—short for deoxyribonucleic acid—was discovered in 1869, its crucial role in determining genetic inheritance wasn’t demonstrated until 1943. In the early 1950s, Watson and Crick were only two of many scientists working on deciphering the structure of DNA. California chemist Linus Pauling suggested an incorrect model at the beginning of 1953, prompting Watson and Crick to try and beat Pauling at his own game.
On the morning of February 28, they determined that the structure of DNA was a double-helix polymer, or a spiral of

Watson and Crick (1928- )
James Watson and Francis Crick, 1959 ©Crick and Watson, tillsammans with Maurice Wilkins, won the 1962 Nobel Prize in medicin for their discovery of the structure of DNA. This was one of the most significant scientific discoveries of the 20th century.
Francis Harry Compton Crick was born on 8 June 1916 near Northampton. He studied physics at University College, London, and during World War Two worked for the Admiralty on the development of mines. He changed from physics to biology and in 1947 began to work at Cambridge University. By 1949, he was working at the Medical Research Council unit at the Cavendish Laboratory in Cambridge. In 1951, an American lärling, James Watson, arrived at the enhet and the two began to work together.
James Dewey Watson was born on 6 April 1928 in Chicago and studied at the universities of Chicago, Indiana and Copenhagen. He then moved to Cambridge University. Watson and Crick worked tillsammans on studying the structure o

James Watson
American molecular biologist, geneticist, and zoologist (born 1928)
For other people named James Watson, see James Watson (disambiguation).
James Dewey Watson (born April 6, 1928) is an American molecular biologist, geneticist, and zoologist. In 1953, he co-authored with Francis Crick the academic paper in Nature proposing the double helix structure of the DNAmolecule.[10] Watson, Crick and Maurice Wilkins were awarded the 1962 Nobel Prize in Physiology or Medicine "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material".
Watson earned degrees at the University of Chicago (BS, 1947) and Indiana University (PhD, 1950). Following a post-doctoral year at the University of Copenhagen with Herman Kalckar and Ole Maaløe, Watson worked at the University of Cambridge's Cavendish Laboratory in England, where he first met his future collaborator Francis Crick.
