Her work was a crucial part in the discovery of dna's structure, which along with subsequent related work led to francis crick, james watson, and maurice wilkins being awarded a nobel prize in 1962 she had died in 1958, and during her lifetime the dna structure was not considered as fully proven. Franklin's images allowed james watson and francis crick to create their famous two-strand, or double-helix, model in 1962 watson (b 1928), crick (1916-2004), and wilkins (1916-2004) jointly received the nobel prize in physiology or medicine for their 1953 determination of the structure of deoxyribonucleic acid (dna.

As a theorist in a science based on experiment, francis crick, more than any other single scientist, defined the field of molecular biology during its classical period from the discovery of the double helical structure of deoxyribonucleic acid (dna) in 1953 to the elucidation of the complete genetic code in 1966.
James d watson became a controversial figure later in life, but this story recounts the seminal event in his life: the 1953 discovery of the structure of dna for which he received the 1962 nobel prize in physiology with his collaborator francis crick and another, maurice wilkins.

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.
Francis crick, in full francis harry compton crick, (born june 8, 1916, northampton, northamptonshire, england—died july 28, 2004, san diego, california, us), british biophysicist, who, with james watson and maurice wilkins, received the 1962 nobel prize for physiology or medicine for their determination of the molecular structure of deoxyribonucleic acid (dna), the chemical substance. Rosalind franklin was a scientist whose contributions to the discovery of the biography & discovery of dna structure by mary james watson and francis crick shared the nobel prize with. Nobel laureate james watson opens ted2005 with the frank and funny story of how he and his research partner, francis crick, discovered the structure of dna. The people responsible for the discovery of dna by brian allensby 1995 the people responsible for the discovery of the double-helical structure of dna were francis crick, rosalind franklin, linus pauling, james watson and maurice wilkins. Friedrich miescher and the discovery of dna characterization of dna by james watson and francis crick with an understanding its structure and how it.
Discovery of the structure of dna on the last day of february in 1953, according to james watson, francis crick announced to the patrons of the eagle pub in cambridge, we have discovered the secret of life (watson 115, 1980. 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.
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.
