Which one of these scientists used X-ray diffraction to study DNA?
A
James Watson
B
Francis Crick
C
Rosalind Franklin
Explanation: 

Detailed explanation-1: -At King’s College in London, Rosalind Franklin and Maurice Wilkins were studying DNA. Wilkins and Franklin used X-ray diffraction as their main tool–beaming X-rays through the molecule yielded a shadow picture of the molecule’s structure, by how the X-rays bounced off its component parts.

Detailed explanation-2: -Rosalind Franklin used X-ray diffraction to determine the structure of DNA molecules. One of her best X-ray pictures is numbered Photo 51 and is shown in Fig. 1(a). This photo was instrumental to J. D. Watson and F.

Detailed explanation-3: -She is best known for an X-ray diffraction image that she and her graduate student Raymond Gosling published in 19531, which was key to the determination of the DNA double helix. But Franklin’s remarkable work on DNA amounts to a fraction of her record and legacy.

Detailed explanation-4: -Our university was dedicated in 2004 to Rosalind Franklin, PhD, the brilliant and trailblazing scientist whose Photo 51 revealed the double helix of DNA-a discovery that was essential in unlocking the mystery to how life is passed down from generation to generation. Dr.

Detailed explanation-5: -At King’s College London, Rosalind Franklin obtained images of DNA using X-ray crystallography, an idea first broached by Maurice Wilkins. Franklin’s images allowed James Watson and Francis Crick to create their famous two-strand, or double-helix, model.
