70 years ago, 3 papers appeared in @Nature under the title ‘Molecular structure of nucleic acids’. In an article in Nature today (link at end) @nccomfort and I shed new light on ‘what Watson and Crick really took from Rosalind Franklin’. This thread summarises our findings. 1/23 @Nature @nccomfort Many ppl believe that Watson and Crick stole Franklin’s data when Watson glimpsed Photograph 51. Told in Watson’s The Double Helix (1968), this is not true (NC, forthcoming, shows the book is semi-fictional). But Photograph 51 is widespread in culture, eg on a UK 50p piece. 2/23
