How did Crick contribute to the discovery of DNA?
Content. Francis Crick (1916-2004) was one of Britain’s great scientists. He is best known for his work with James Watson which led to the identification of the structure of DNA in 1953, drawing on the work of Maurice Wilkins, Rosalind Franklin and others.
Did Watson and Crick discover DNA by themselves?
Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s. In reality, this is not the case. Rather, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher.
Who were Watson and Crick and what did they do?
Watson and Crick worked together on studying the structure of DNA (deoxyribonucleic acid), the molecule that contains the hereditary information for cells. At that time Maurice Wilkins and Rosalind Franklin, both working at King’s College, London, were using X-ray diffraction to study DNA.
How did DNA get its name?
DNA gets its name from the sugar molecule contained in its backbone(deoxyribose); however, it gets its significance from its unique structure. Four different nucleotide bases occur in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T).
Where did Watson and Crick discover DNA?
Cambridge University
On February 28, 1953, Cambridge University scientists James D. Watson and Francis H.C. Crick announce that they have determined the double-helix structure of DNA, the molecule containing human genes.
What did Watson say?
Watson told a British reporter with the Sunday Times that “all our social policies are based on the fact that African intelligence is the same as ours, whereas all the testing says not really.” He added that he hoped everyone was equal — “but people who have to deal with black employees find this not true.”
What did Watson discover?
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.
