James Watson, Co-discoverer of DNA Double Helix, Dies at 97
James Watson, an American molecular biologist who won the Nobel Prize in 1962 for co-discovering the double-helix structure of DNA, has died at the age of 97. His work was crucial in enabling the mapping of the human genome and transforming our understanding of genetics.
Pioneering Discovery of DNA Structure
In spring 1953, Watson and fellow scientist Francis Crick published their description of the double-helix structure of deoxyribonucleic acid in the British journal Nature. This discovery revealed the molecule carrying genetic information in all living organisms, revolutionizing the study of evolution and inherited diseases.
"I made the discovery of the century. Suddenly to see the molecule which is responsible for heredity, and which makes possible human existence, was a very big step in man's understanding of himself in the same sense that Darwin knew that the human species wasn't fixed, that we were changing. It was bound to affect your attitude to everything."
Legacy and Controversies
Watson was widely celebrated as a genetics pioneer alongside Crick. However, his reputation was later marred by allegations of uncredited contributions by others and by his racist and sexist remarks, which cast a shadow over his legacy.
Impact on Science and Society
- The DNA double helix discovery was foundational for genetics and molecular biology.
- It changed scientific views on evolution and hereditary diseases.
- Watson's remarks sparked significant controversy despite his scientific achievements.
Author’s summary: James Watson's critical discovery of DNA’s structure reshaped science, though later controversies around his personal views have complicated his legacy.
