J.S. Watson

J.S. Watson is a renowned American scientist best known for his role in discovering the structure of DNA. Working alongside Francis Crick in the 1950s, Watson used X-ray diffraction images—particularly Photo 51—to determine that DNA is a double helix. This groundbreaking discovery explained how genetic information is stored and replicated in living organisms, revolutionizing biology and medicine. Watson's work provided a foundation for understanding genetics, heredity, and even developments like genetic engineering. His contributions are considered pivotal in the biological sciences, advancing our comprehension of life's molecular blueprint.
