Unravelling DNA's structure: a landmark achievement whose authors were not fairly credited

This knowledge of DNA allowed for a deeper understanding of how DNA stores information and how it is replicated.

Key Points: 
  • This knowledge of DNA allowed for a deeper understanding of how DNA stores information and how it is replicated.
  • For most of the past 70 years the names Watson and Crick have been synonymous with DNA.
  • And the three papers were the result of direct input from seven authors: Rosalind Franklin, Raymond Gosling, Maurice Wilkins, Alec Stokes, Herbert Wilson, James Watson and Francis Crick.

Nevertheless she persisted

    • In Watson’s 1968 book The Double Helix he frequently disparages Franklin, making negative comments about her appearance, her feminist principles and her emotions.
    • It was a photograph generated by shining x-rays through a crystal of DNA, using a technique called x-ray crystallography.
    • The image is known as Photo 51, and it contained critical information on the physical dimensions of DNA.

Things could have been different

    • One based in King College London, which included Wilkins and Franklin.
    • The article describes an exchange of information, including Franklin “checking the Cavendish model against her own x-rays’ data”.

Unlocking the role of DNA

    • Without an understanding of DNA’s role in biology Watson and Crick would not have been at all interested in DNA.
    • She produced the first x-ray images of DNA.
    • Bell’s work also gave her an inkling of DNA’s critical role in biology.
    • They used bacteriophages, viruses that infect bacteria, to show that DNA, not proteins, carried genetic information.

Taking the credit

    • The male authors of the 1953 DNA paper enjoyed long careers in academia.
    • But Chase only had a brief spell as a researcher before losing her job, for reasons that are unclear.
    • Franklin’s achievements were cut short by her death from ovarian cancer in 1958 at the age of 37.
    • And Elizabeth Fulhame introduced to science the concept of catalysis, 40 years before its “discovery” by Jons Jakob Berzelius in 1835.
