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.
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. [11] 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.
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.
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.
Watson and Crick used characteristics and features of Photo 51, together with evidence from multiple other sources, to develop the chemical model of the DNA molecule. Their model, along with papers by Wilkins and colleagues, and by Gosling and Franklin, were first published, together, in 1953, in the same issue of Nature.
Coming across Gamow's paper, Crick immediately noticed some issues in the scheme. The first was that he and Watson never had before counted the 20 amino acids or the possible 20 nucleotide triplets [19] (although Gamow was subsequently proven to be correct and his model was the first prediction of the genetic code [17] [23]). The other issue ...
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 called this problem "the mystery of life" in his letter to Crick. [5] Soviet-American physicist George Gamow at George Washington University suggested the first scheme for protein synthesis from DNA. [7] [8] In early 1954, he spent several days at Woods Hole on Cape Cod with Crick, Watson and Sydney Brenner, discussing genetics. [2]
