James Watson and Francis Crick were the first to propose the structure of DNA as a twisted-ladder molecule with complementary base pairing. They based their model on the experimental results of others and used the method of model building to uncover the secret of heredity.
28 de jul. de 2022 · At King’s College London, Rosalind Franklin obtained images of DNA using X-ray crystallography, an idea first broached by Maurice Wilkins. 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 ...
Watson is a U.S. molecular biologist, geneticist and zoologist, best known as one of the co-discoverers of the structure of DNA in 1953 with Francis Crick . In 1998, the Modern Library placed The Double Helix at number 7 on its list of the 100 best nonfiction books of the 20th century.

Franklin is best known for her work on the X-ray diffraction images of DNA while at King's College London, particularly Photo 51, taken by her student Raymond Gosling, which led to the discovery of the DNA double helix for which Francis Crick, James Watson, and Maurice Wilkins shared the Nobel Prize in Physiology or Medicine in 1962.
Learn how James Watson, Francis Crick, Rosalind Franklin, and Maurice Wilkins revealed the double helix structure of DNA through X-ray crystallography and other data. Explore the components, properties, and significance of DNA as the genetic material.
In mid-March 1953, Watson and Crick deduced the double helix structure of DNA. Crucial to their discovery were the experimental data collected at King's College London—mainly by Rosalind Franklin for which they did not provide proper attribution.
