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.

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.
Whether Franklin would have deduced the structure of DNA on her own, from her own data, had Watson and Crick not obtained Gosling's image, is a hotly debated topic, [11] [16] [18] [19] made more controversial by the negative caricature of Franklin presented in the early chapters of Watson's history of the research on DNA structure, The Double ...
In 1953, James Watson and Francis Crick discovered the double helical structure of the DNA molecule based on the discoveries made by Rosalind Franklin. [5] In 1961, François Jacob and Jacques Monod demonstrated that the products of certain genes regulated the expression of other genes by acting upon specific sites at the edge of those genes.
In the film, Watson, extolling the path of intuition, says: "Blessed are they who believed before there was any evidence." It also shows how Watson and Crick made their discovery, overtaking their competitors in part by reasoning from genetic function to predict chemical structure, helping to establish the field of molecular biology.
Watson is a U.S. molecular biologist, geneticist and zoologist, best known as one of the co-discoverers of the structure of DNA in 1953 with Francis Crick. In 1998, the Modern Library placed The Double Helix at number 7 on its list of the 100 best nonfiction books of the 20th century.
The double-helix model of DNA structure was first published in the journal Nature by James Watson and Francis Crick in 1953, [6] (X,Y,Z coordinates in 1954 [7]) based on the work of Rosalind Franklin and her student Raymond Gosling, who took the crucial X-ray diffraction image of DNA labeled as "Photo 51", [8] [9] and Maurice Wilkins, Alexander Stokes, and Herbert Wilson, [10] and base-pairing ...
