The Genetics Revolution spans from the discovery of DNA's double-helix structure in 1953 to the completion of the Human Genome Project in 2003 — and continues today with CRISPR gene editing and personalised medicine. It fundamentally changed our understanding of life, heredity, and disease. Within 50 years, humanity went from not knowing how genetic information was encoded to reading the entire human blueprint, opening the door to targeted therapies, genetic screening, and the eventual ability to edit the code of life itself.
