Pub to DNA: Cracking Life's Code

February 2023
University of Cambridge

Introduction

Imagine popping into a pub and announcing you've just unlocked the "secret of life"! That's exactly what James Watson and his colleague did in Cambridge, after figuring out DNA's structure. This game-changing moment 70 years ago at the Cavendish Laboratory wasn't just their win; it was a victory lap for a team of brilliant minds, including the unsung hero, Rosalind Franklin. Their discovery has since revolutionized our understanding of genetics and disease. Dive into this thrilling story from the University of Cambridge and get inspired by the blend of teamwork, rivalry, and sheer genius that cracked the code of life!
