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.

After the discovery of the double helix model of DNA, Crick's interests quickly turned to the biological implications of the structure. In 1953, Watson and Crick published another article in Nature which stated: "it therefore seems likely that the precise sequence of the bases is the code that carries the genetical information". [61]
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 ...
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 ...
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". [209] Pencil sketch of the DNA double helix by Francis Crick in 1953. The 25 April 1953 issue of the journal Nature published a series of five articles giving the Watson and Crick ...
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.
