Today in Chemistry History – Rosalind Franklin and the structure of DNA

Rosalind Franklin was born on this day in 1920. Her contributions to the discovery of the structure of DNA were key; she took photos of DNA’s structure using X-ray crystallography, and it was these photos which informed the work of Watson and Crick’s model of DNA’s structure. Sadly her contributions were not fully recognised until […]
