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 in her lifetime ...
5 days ago · Rosalind Franklin (born July 25, 1920, London, England—died April 16, 1958, London) was a British scientist best known for her contributions to the discovery of the molecular structure of deoxyribonucleic acid ( DNA ), a constituent of chromosomes that serves to encode genetic information. Franklin also contributed new insight on the ...

- Franklin and DNA. In the early 1950s, the structure and function of DNA remained unclear. It had been found in every cell type investigated, and was known to consist of a phosphate backbone to which were attached four kinds of base — adenine, thymine, cytosine and guanine (A, T, C and G).
- The meaning of Photograph 51. Even Franklin’s advocates often unwittingly perpetuate a caricatured view of her science — one that can be traced back to Watson’s reality-distorting 1968 bestseller, The Double Helix8.
- What Franklin really did. Franklin contributed several key insights to the discovery of the double helix. She clearly differentiated the A and B forms, solving a problem that had confused previous researchers.
- Acknowledging the truth. After Watson and Crick had read the MRC report, they could not unsee it. But they could have — and should have — requested permission to use the data and made clear exactly what they had done, first to Franklin and Wilkins, and then to the rest of the world, in their publications.
