Double helix. 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. [4][5][6][7][8] The image was ...
Rosalind Franklin. Rosalind Elsie Franklin (25 July 1920 – 16 April 1958) [1] was a British chemist and X-ray crystallographer whose work was central to the understanding of the molecular structures of DNA (deoxyribonucleic acid), RNA (ribonucleic acid), viruses, coal, and graphite. [2] Although her works on coal and viruses were appreciated ...
Rosalind Franklin joined King's College London in January 1951 to work on the crystallography of DNA. By the end of that year, she established two important facts: one is that phosphate groups, which are the molecular backbone for the nucleotide chains, lie on the outside (it was a general consensus at the time that they were at the inside); and the other is that DNA exists in two forms, a ...
Maurice Hugh Frederick Wilkins CBE FRS (15 December 1916 – 5 October 2004) [2] was a New Zealand -born British biophysicist and Nobel laureate whose research spanned multiple areas of physics and biophysics, contributing to the scientific understanding of phosphorescence, isotope separation, optical microscopy, and X-ray diffraction.
Raymond George Gosling (15 July 1926 – 18 May 2015) was a British scientist. While a PhD student at King's College, London he worked under the supervision of Maurice Wilkins and Rosalind Franklin. The crystallographic experiments of Franklin and Gosling, together with others by Wilkins, produced data that helped James Watson and Francis Crick ...
Lifelong researcher Rosalind Franklin discovered the existence of a helix formation made of molecules during her research on X-ray diffraction in 1951. Two years later, James Watson and Francis ...
X-ray diffraction is a generic term for phenomena associated with changes in the direction of X-ray beams due to interactions with the electrons around atoms. It occurs due to elastic scattering, when there is no change in the energy of the waves. The resulting map of the directions of the X-rays far from the sample is called a diffraction pattern.
Photograph 51 is a play by Anna Ziegler. Photograph 51 opened in the West End of London in September 2015. [1] The play focuses on the often-overlooked role of X-ray crystallographer Rosalind Franklin in the discovery of the double helix structure of DNA while working at King's College London. [2][3] This play won the third STAGE International ...
