Watson and Crick used many aluminium templates like this one, which is the single base Adenine (A), to build a physical model of DNA in 1953. When Watson and Crick produced their double helix model of DNA, it was known that most of the specialized features of the many different life forms on Earth are made possible by proteins.
The Double Helix: A Personal Account of the Discovery of the Structure of DNA is an autobiographical account of the discovery of the double helix structure of DNA written by James D. Watson and published in 1968. It has earned both critical and public praise, along with continuing controversy about credit for the Nobel award and attitudes ...
Francis Harry Compton Crick OM FRS [3] [4] (8 June 1916 – 28 July 2004) was an English molecular biologist, biophysicist, and neuroscientist.He, James Watson, Rosalind Franklin, and Maurice Wilkins played crucial roles in deciphering the helical structure of the DNA molecule.
Based on the Watson-Crick model, he envisaged that the DNA itself is a direct template for protein synthesis. [18] Assuming that the four bases of DNA could produce 20 different combinations as triplets, he suggested that the different amino acids must correspond to a twenty-letter alphabet of the nucleotide sequence. [19]
The first reports of a double helix molecular model of B-DNA structure were made by James Watson and Francis Crick in 1953. [5] [6] That same year, Maurice F. Wilkins, A. Stokes and H.R. Wilson, reported the first X-ray patterns of in vivo B-DNA in partially oriented salmon sperm heads. [7]
In 1953, English biophysicist Francis Crick and American biologist James Watson, working together at the Cavendish Laboratory of the University of Cambridge, deduced the structure of DNA, the principal genetic material of organisms, [3] thought to link genetic information in DNA to proteins. [4]
The wording on the DNA sculpture (donated by James Watson) outside Clare College's Thirkill Court, Cambridge, England is a) on the base: i) "These strands unravel during cell reproduction. Genes are encoded in the sequence of bases." ii) "The double helix model was supported by the work of Rosalind Franklin and Maurice Wilkins." b) on the helices:
