• maurice wilkins and rosalind franklin at king's college in london • linus pauling, an american chemist at the california institute of technology • james watson and francis crick at cambridge. In 1953, both wilkins and franklin published papers on their x-ray data in the same nature issue with watson and crick's paper on the structure of dna franklin left cambridge in 1953 and went to the birkbeck lab to work on the structure of tobacco mosaic virus. The x-ray diffraction photography of rosalind franklin and maurice wilkins was critical evidence of indicating that dna has a double helix structure in the watson and crick model of dna, the steps of the ladder are composed of. For instance, the uk national curriculum key stage 3 (ages 11-14) suggests the teaching of 'a simple model of chromosomes, genes and dna in heredity, including the part played by watson, crick, wilkins and franklin in the development of the dna model.
The story of dna is a tale of competition and intrigue, told one way in james watson's book the double helix, and quite another in anne sayre's study, rosalind franklin and dna james watson, francis crick, and maurice wilkins received a nobel prize for the double-helix model of dna in 1962, four years after franklin's death at age 37 from. Rosalind franklin, the biophysicist whose work provided the scientific support for watson and crick's development of the structure of dna, has remained a mystery, her opinions and motivations hidden. This was, in fact, the dna which rosalind franklin used in her x-ray diffraction studies that rewarded maurice wilkins , james watson and francis crick with the nobel prize for the double helix model of dna. On july 25, 1920 the english biophysicist rosalind franklin was born she was instrumental in discovering the molecular structure of dna, though her vital contributions were only posthumously.
Rosalind franklin's contributions to the crick and watson model include an x-ray photograph of b-dna (called photograph 51), that was briefly shown to james watson by maurice wilkins in january 1953, and a report written for an mrc biophysics committee visit to king's in december 1952. Maurice wilkins biography physicist, academic, biologist, scientist (1916-2004) biophysicist maurice wilkins was known for his contributions to the discovery of dna's molecular structure, for. First, rosalind franklin and maurice wilkins had amassed x-ray diffraction data on dna structure in such experiments, x rays are fired at dna fibers, and the scatter of the rays from the fiber is observed by catching them on photographic film, where the x rays produce spots.
Rosalind franklin (1920-1958) was a british biophysicist and x-ray crystallographer her discoveries related to the molecular structure of coal and carbon were used to develop strong carbon fibers and slow reactions in nuclear power plants. The people responsible for the discovery of dna by brian allensby 1995 the people responsible for the discovery of the double-helical structure of dna were francis crick, rosalind franklin, linus pauling, james watson and maurice wilkins. Maurice wilkins and rosalind franklin maurice wilkins and rosalind franklin, together with ray gosling, alec stokes and herbert wilson and other colleagues at the randall institute at king's, made crucial contributions to the discovery of dna's structure in 1953.
Dna was first crystallized in the late 70's — remember, the 1953 x-ray data were from dna fibers so, the real proof for the watson-crick model of dna came in 1982 after the b-form of dna was crystallized and the x-ray pattern was solved. British chemist rosalind franklin is best known for her role in the discovery of the structure of dna, and for her pioneering use of x-ray diffraction.
Rosalind elsie franklin (25 july 1920 - 16 april 1958) was an english chemist and x-ray crystallographer who made contributions to the understanding of the molecular structures of dna (deoxyribonucleic acid), rna (ribonucleic acid), viruses, coal, and graphite. Anything that is said about rosalind franklin, first it's wilkins and then it's franklin, and then it is, but of course we didn't really need that data, we used stereochemistry and models. Wilkins and franklin did the actual experimental work watson and crick built models based on theories they developed from their understanding of the experiments jobs of dna -carries information from one generation to the next by coding for traits. Public unveiling of frieze celebrating rosalind franklin and maurice wilkins work at king's college london on the 13th september 2010 principal professor rick trainor unveiled the newly designed dna frieze outside the franklin-wilkins building on the waterloo campus.
