Rosalind Franklin, British scientist best known for her contributions to the discovery of the molecular structure of DNA. Franklin also contributed new insight on the structure of viruses, helping to lay the foundation for the field of structural virology. Learn about her life and career.
Rosalind Franklin was a chemist and X-ray crystallographer who studied DNA at King’s College London from 1951 to 1953, and her unpublished data paved the way for Watson and Crick’s...
With the Signer DNA, Franklin was able to exploit a discovery that Wilkins had made earlier — DNA in solution could take two forms, what she called the crystalline or A form, and the ...
Rosalind Franklin was a chemist and X-ray crystallographer whose data contributed to the discovery of DNA’s molecular structure. That data wasn’t stolen from her, newly uncovered evidence ...
Franklin is best known for her work on the X-ray diffraction images of DNA while at King's College London, particularly Photo 51, taken by her student Raymond Gosling, which led to the discovery of the DNA double helix for which Francis Crick, James Watson, and Maurice Wilkins shared the Nobel Prize in Physiology or Medicine in 1962. [10][11] Wh...
The two scientists did, in fact, use what they saw in Photo 51 as the basis for their famous model of DNA, which they published on March 7, 1953, and for which they received a Nobel Prize in...
The discovery of the structure of DNA in 1953 was made possible by Dr Rosalind Franklin’s X-ray diffraction work at King’s. Her creation of the famous Photo 51 demonstrated the double-helix structure of deoxyribonucleic acid: the molecule containing the genetic instructions for the development of all living organisms.
While a lot of Rosalind Franklin's work used X-ray crystallography she also used other X-ray diffraction techniques. Her famous image of DNA called Photo 51 was made using a X-ray technique that did not require the sample to be in crystal form.
While working at the King's College London in 1951, she discovered two types of DNA called A-DNA and B-DNA. Her X-ray images of DNA indicated helical structure. Her X-ray image of B-DNA (called Photo 51) taken in 1952 became the best evidence for the structure of DNA.
Franklin’s image confirmed James Watson and Francis Crick of the University of Cambridge's hypothesis that DNA had a double helical structure, enabling them to build the first correct model of the DNA molecule in 1953.
