Francis Crick
English physicist, molecular biologist; co-discoverer of the structure of DNA
Francis Harry Compton CrickOM 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.
Crick and Watson's paper in Nature in 1953 laid the groundwork for understanding DNA structure and functions.[5] Together with Maurice Wilkins, they were jointly awarded the 1962 Nobel Prize in Physiology or Medicine "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material".[2][6]
Crick was an important theoretical molecular biologist and played a crucial role in research related to revealing the helical structure of DNA. He is widely known for the use of the term "central dogma" to summarise the idea that once information is transferred from nucleic acids (DNA or RNA) to proteins, it cannot flow back to nucleic acids. In other words, the final step in the flow of information from nucleic acids to proteins is irreversible.[7]
During the remainder of his career,

At King’s College London, Rosalind Franklin obtained images of DNA using X-ray crystallography, an idea first broached by Maurice Wilkins. Franklin’s images allowed James Watson and Francis Crick to create their famous two-strand, or double-helix, model.
In 1962 Watson (b. 1928), Crick (1916–2004), and Wilkins (1916–2004) jointly received the Nobel Prize in Physiology or Medicine for their 1953 determination of the structure of deoxyribonucleic acid (DNA). Wilkins’s colleague Franklin (1920–1958), who died from cancer at the age of 37, was not so honored. The reasons for her exclusion have been debated and are still unclear. There is a Nobel Prize stipulation that states “in no case may a prize amount be divided between more than three persons.” The fact she died before the prize was awarded may also have been a factor, although the stipulation against posthumous awards was not instated until 1974.
Discovering the Structure of DNA
The molecule that is the basis for heredity, DNA, contains the patterns for constructing proteins in the body, including the various enzymes. A new understanding of heredity and hereditary disease was possible once it was determined that DNA consists of two chains twisted around each other, or double helixes, of alternating phosphate and sugar gro
