DNA model built by Crick and Watson in 1953, in the Science Museum, London. In mid-March 1953, Watson and Crick deduced the double helix structure of DNA. [13] Crucial to their discovery were the experimental data collected at King's College London—mainly by Rosalind Franklin for which they did not provide proper attribution.
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 ...
Watson and Crick's calculations from Gosling and Franklin's photography gave crucial parameters for the size and structure of the helix. [ 16 ] Photo 51 became a crucial data source [ 17 ] that led to the development of the DNA model and confirmed the prior postulated double helical structure of DNA, which were presented in the series of three ...
Watson and Crick completed their model, which is now accepted as the first correct model of the double helix of DNA. On 28 February 1953 Crick interrupted patrons' lunchtime at The Eagle pub in Cambridge, England to announce that he and Watson had "discovered the secret of life".

The discovery was announced on February 28, 1953; the first Watson/Crick paper appeared in Nature on April 25, 1953. Sir Lawrence Bragg , the director of the Cavendish Laboratory , where Watson and Crick worked, gave a talk at Guy's Hospital Medical School in London on Thursday, May 14, 1953, which resulted in an article by Ritchie Calder in ...
Perutz's justification for passing Franklin's report about the crystallographic unit of the B-DNA and A-DNA structures to both Crick and Watson was that the report contained information which Watson had heard before, in November 1951, when Franklin talked about her unpublished results with Raymond Gosling during a meeting arranged by M.H.F ...
On April 25, 1953 James D. Watson and Francis Crick published "a radically different structure" for DNA, [3] thereby founding the field of molecular genetics. Their structural model featured two strands of complementary base-paired DNA, running in opposite directions as a double helix. They concluded their report saying that "It has not escaped ...
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.
