Watson and Crick

James Watson and Francis Crick were scientists who discovered the double helix structure of DNA in 1953, revolutionizing our understanding of genetic material and laying the foundation for modern molecular biology.

Historical Background

James Watson and Francis Crick's collaboration at the University of Cambridge's Cavendish Laboratory in the early 1950s represents one of the most significant partnerships in scientific history. Their work built upon research by:

The Discovery

The Double Helix Model

In 1953, Watson and Crick proposed the revolutionary double helix structure of DNA, characterized by:

  • Two intertwined strands running in opposite directions
  • base pairs connected by hydrogen bonds
  • A sugar-phosphate backbone
  • Regular helical turns every 3.4 nanometers

Publication and Impact

Their groundbreaking paper in Nature journal:

  • Was remarkably brief (just over one page)
  • Included the famous understatement about DNA's implications for genetic information transfer
  • Led to their sharing the Nobel Prize in Physiology or Medicine (1962)
