Who used X ray diffraction to better understand DNA?
A
Franklin
B
Watson and Crick
C
Chargaff
D
Mendel
Explanation: 

Detailed explanation-1: -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).

Detailed explanation-2: -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.
