Francis harry compton crick om frs (8 june 1916 - 28 july 2004) was a british molecular biologist, biophysicist, and neuroscientist, most noted for being a co-discoverer of the structure of the dna molecule in 1953 with james watson.

The discovery of its molecular structure, by francis crick and james watson, immediately suggested that dna—not a protein, as was widely imagined—was the master molecule that contains the genes, self-replicates and recombines during reproduction. The discovery in 1953 of the double helix, the twisted-ladder structure of deoxyribonucleic acid (dna), by james watson and francis crick marked a milestone in the history of science and gave rise to modern molecular biology, which is largely concerned with understanding how genes control the chemical processes within cells. From the greatest discoveries series (discovery) the moment in which watson and crick discovered the double helix structure of the dna. This short film describes the evidence that led james watson and francis crick to the discovery of the double-helical structure of dna and how the structure immediately revealed how genetic information is stored and inherited.

Dr mark hirst of the open university and prof robert budd, curator of medicine at london's science museum, discuss how francis crick and james watson made their discovery 60 years ago this week. 1953: james watson and francis crick with their model of the double helix, the twisted-ladder structure of deoxyribonucleic acid (dna), the year of their momentous discovery. Maurice wilkins, who played a critical role in discovering the structure of dna but whose contributions were long overshadowed by james watson and francis crick, died tuesday at a london hospital he was 88 the discovery of dna's double helix structure -- considered one of the towering achievements.

  • James watson & francis crick suggest the first correct double-helix model of dna structure 1958 meselson-stahl experiment confirms replication mechanism as implied by the double-helical structure.
  • James watson and francis crick, won the 1962 nobel prize in medicine for their discovery of the structure of dna this was one of the most significant scientific discoveries of the 20th.

The classic personal account of watson and crick's groundbreaking discovery of the structure of dna, now with an introduction by sylvia nasar, author of a beautiful mindby identifying the structure of dna, the molecule of life, francis crick and james watson revolutionized biochemistry and won themselves a nobel prize. There were many scientists that helped discover dna james crick and francis watson are generally credited with its discovery but there were other people who helped leading up to the discovery. Watson (along with francis crick, rosalind franklin, and maurice wilkins) was awarded the nobel prize in physiology or medicine in 1962 for the discovery of the dna structure he continued his research into genetics writing several textbooks as well as the bestselling book the double helix which chronicled the famous discovery. Franklin's image of the dna molecule was key to deciphering its structure, but only watson, crick, and wilkins received the 1962 nobel prize in physiology or medicine for their work.
