1952 – London, England
‘Description of the basic helical structure of the DNA molecule’
Her work is used, unaccredited, in Watson & Crick’s Nobel Prize-winning paper, from information ‘secretly’ leaked from Maurice Hugh Frederick Wilkins.
Through her work on X-ray diffraction, she realised that the ‘backbone’ of the DNA molecule was on the outside.
By 1952, Franklin had taken the clearest pictures of the molecules to date, which provided evidence of a helical, or spiral structure.
Watson & Crick would eventually articulate a ‘double-helix’ construction.
