Rosalind Franklin and the Discovery of DNA

The video explores the post-WWII race to discover DNA's structure, highlighting Rosalind Franklin's crucial yet underappreciated role. Despite her groundbreaking work at King's College, Franklin faced gender and social barriers. Her Photo 51 was pivotal for Watson and Crick's model, yet she received little credit. Franklin's later work on viruses further cemented her scientific legacy.
