Who is the co discoverer of DNA structure?
James Dewey Watson
James Dewey Watson (1928–): Co-discoverer of the structure of DNA.
What did James Watson work on after discovering the structure of DNA?
Watson is credited with the discovery of the double-helix structure of DNA along with Francis Crick. Watson received a 1962 Nobel Prize and went on to do work in cancer research and mapping the human genome.
Who helped Crick and Watson puzzle out the structure of DNA?
Chargaff’s realization that A = T and C = G, combined with some crucially important X-ray crystallography work by English researchers Rosalind Franklin and Maurice Wilkins, contributed to Watson and Crick’s derivation of the three-dimensional, double-helical model for the structure of DNA.
How did James Watson describe the structure of DNA?
In 1953 James Watson and Francis Crick published their theory that DNA must be shaped like a double helix. A double helix resembles a twisted ladder. Each ‘upright’ pole of the ladder is formed from a backbone of alternating sugar and phosphate groups.
Where is James Watson from?

How do the discoverers come to their conclusion about the structure of DNA?
Created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule. Watson and Crick realized that DNA was made up of two chains of nucleotide pairs that encode the genetic information for all living things.
Where is James Watson today?
Watson’s accomplishment is displayed on the monument at the American Museum of Natural History in New York City. Because the monument memorializes only American laureates, Francis Crick and Maurice Wilkins (who shared the 1962 Nobel Prize in Physiology or Medicine) are omitted.
Who did James Watson marry?
Elizabeth Watsonm. 1968
James D. Watson/Spouse
. In 1968 he married Elizabeth Lewis with whom he had two sons, one of whom developed schizophrenia. His son’s disease awakened Watson’s interest in understanding the genetics behind the disease.
Why was Watson and Crick’s first model incorrect?
Watson and Crick’s model erroneously placed the bases on the outside of the DNA molecule with the phosphates, bound by magnesium or calcium ions, inside. One of the key characteristics of science is that it relies on evidence.
What do you call this structure of DNA?
The double helix is a description of the molecular shape of a double-stranded DNA molecule. In 1953, Francis Crick and James Watson first described the molecular structure of DNA, which they called a “double helix,” in the journal Nature.
What is the key feature of DNA that allows it to be copied?
DNA can replicate itself because of the way its double strands relate to one another. The purines and pyrimidines that join the two strands pair exclusively with only one other base. This ensures that when the DNA strands separate to replicate an exact copy is created.
What did Watson discover about DNA?
Suddenly, in the spring of 1953, Watson saw that the essential DNA components—four organic bases—must be linked in definite pairs. This discovery was the key factor that enabled Watson and Crick to formulate a molecular model for DNA—a double helix, which can be likened to a spiraling staircase or a twisting ladder.
What did James Watson contribute to the discovery of DNA?
James Watson Biography: Co-Discoverer of DNA’s Double Helix. James Watson was a pioneer molecular biologist who is credited, along with Francis Crick and Maurice Wilkins, with discovering the double helix structure of the DNA molecule. The trio won the Nobel Prize in Medicine in 1962 for their work.
What did James Watson and Francis Crick discover in 1953?
At midday on 28 February 1953, Francis Crick and James Watson walked into The Eagle pub in Cambridge and announced “We have discovered the secret of life.” Earlier that morning, in the nearby Cavendish laboratory, the two scientists had discovered the structure of deoxyribonucleic acid, or DNA.
What did James Watson do in the Cavendish Laboratory?
Watson, excited by Wilkins’ results, moved to England in the fall. He went to work at Cavendish Laboratory where he began working with Francis Crick. Watson and Crick decided to use a model-building approach to try to discern the molecular structure of the DNA molecule.
Who is James Dewey Watson?
James Dewey Watson is an American scientist who is one of the co-discoverers of the structure of DNA. A Nobel prize winner, Watson’s life has been dedicated to the study of the human gene. James is born. James Dewey Watson is born on April 6, 1928 in St. Luke’s Hospital in Chicago, Illinois. His parents are James D. Watson and Jean Mitchell.
