James Watson (co-discoverer of DNA structure)

James Watson is an American molecular biologist best known for co-discovering the double helix structure of DNA alongside Francis Crick in 1953. Their groundbreaking work revealed how genetic information is stored and transmitted in living organisms, fundamentally changing the field of genetics and biology. Watson's contributions helped lay the foundation for modern genetics, including breakthroughs in medicine and biotechnology. He was awarded the Nobel Prize in Physiology or Medicine in 1962 for this achievement, which remains one of the most significant scientific discoveries of the 20th century. Watson has also authored several books on science and genetics.
