Rosalind Franklin was a British molecular biologist who was instrumental in the discovery of the structure of deoxyribonucleic acid in 1951. At King's College London where she applied X-ray diffraction to the study of biological materials, she performed several X-ray radiographs of the DNA. Sex chromosomes
Rosalind Franklin and DNA is a biography of an English chemist Rosalind Franklin (1920–1958) written by her American friend Anne Sayre in 1975. Franklin was a physical chemist who made pivotal research in the discovery of the structure of DNA, known as "the most important discovery" in biology.
Photo 51 is an X-ray based fiber diffraction image of a paracrystalline gel composed of DNA fiber [1] taken by Raymond Gosling, [2] [3] a postgraduate student working under the supervision of Maurice Wilkins and Rosalind Franklin at King's College London, while working in Sir John Randall's group.
1952: an X-ray diffraction image of DNA was taken by Raymond Gosling in May 1952, a student supervised by Rosalind Franklin. [30] 1953: DNA structure is resolved to be a double helix by James Watson, Francis Crick and Maurice Wilkins. [31] 1955: Alexander R. Todd determined the chemical makeup of nitrogenous bases.
Rosalind Franklin (1920–1957), British physical chemist and crystallographer [4]: 82–89 Ellen Gleditsch (1879–1968), Norwegian radiochemist [5] Jenny Glusker (born 1931), British biochemist, educator; Emīlija Gudriniece (1920–2004), Latvian chemist and academic
In 1952, Rosalind Franklin and Raymond Gosling produced a strikingly clear x-ray diffraction pattern indicating a helical form. Using these x-rays and information already known about the chemistry of DNA, James D. Watson and Francis Crick demonstrated the molecular structure of DNA in 1953.
1953: James Watson, Francis Crick, Maurice Wilkins and Rosalind Franklin: helical structure of DNA, basis for molecular biology; 1957: Chien Shiung Wu: demonstrated that parity, and thus charge conjugation and time-reversals, are violated for weak interactions; 1962: Riccardo Giacconi and his team discover the first cosmic x-ray source ...
