Rosalind Franklin Announces the Death of the Helix

If you've read The Story of DNA (Part 1) you'll know that we've reached the point in November 1951 where Watson and Crick have failed in their first attempt. Rosalind Franklin was more than happy to point out how little they knew about the chemistry of DNA.

In Part 2 we'll learn how Watson and Crick redeemed themselves and how they we able to turn the tables on Rosalind Franklin. This notice, which was sent out to everyone in London and Cambridge who were interested in DNA, was signed by Raymond Gosling and Rosalind Franklin. It announces that DNA is NOT a helix. The date is July 18, 1952.
