Who is Rosalind Franklin? Born on July 25, 1920 in London, England, Rosalind Elise Franklin was a catalyst to many other scientists in the field of genetics. Using coal and carbon as subjects, Franklin discovered the double helix of DNA, the shape that two linear strands of DNA assume when bonded together. In 1945, Franklin received her Ph. D in physical chemistry from Cambridge University. The next year she went to Paris and worked in the Laboratoire Central …showed first 75 words of 780 total…

She laid the basis for the quantitative study of the diffraction patterns, and after the formation of the Watson - Crick model she demonstrated that a double helix was consistent with the X-ray patterns of both the A and B forms.” Sir Aaron Klug is known for his development of crystallographic electron microscopy and his structural elucidation of biologically important nuclei acid-protein complexes.
