Who co discovered the structure of DNA?
Who co discovered the structure of DNA?
James Watson
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.
Who was the British scientist who co discovered the structure of the DNA molecule in the 1950s?
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 …
What were Franklin and Wilkins known for?
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). Wilkins’s colleague Franklin (1920–1958), who died from cancer at the age of 37, was not so honored.
What did Wilkins do for DNA?
Wilkins is most well-known for beginning the X-ray diffraction images of DNA that contributed to Watson and Crick’s discovery of the double-helix structure of DNA.
What did Wilkins and Franklin discover about DNA?
At King’s College in London, Rosalind Franklin and Maurice Wilkins were studying DNA. Wilkins and Franklin used X-ray diffraction as their main tool — beaming X-rays through the molecule yielded a shadow picture of the molecule’s structure, by how the X-rays bounced off its component parts.
When did Maurice Wilkins discover DNA?
1953
Lived 1916 – 2004. Maurice Wilkins initiated the experimental research into DNA that culminated in Watson and Crick’s discovery of its structure in 1953. Wilkins crystallized DNA in a form suitable for quantitative X-ray diffraction work and obtained the best quality X-ray images seen at that time.
What was Rosalind Franklin’s contribution to Watson and Crick’s discovery of DNA structure?
Rosalind Franklin discovered the density of DNA and, more importantly, established that the molecule existed in a helical conformation. Her work to make clearer X-ray patterns of DNA molecules laid the foundation for James Watson and Francis Crick’s suggestion that DNA is a double-helix polymer in 1953.
What did Francis Crick discover about DNA?
http://dx.doi.org/10.1371/journal.pbio.0020419. Francis Crick was a pioneer molecular biologist who is credited, along with James Watson 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.
Who discovered the double helix of DNA?
Francis Crick: Co-Discoverer of DNA’s Double Helix. Francis Crick was a pioneer molecular biologist who is credited, along with James Watson 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.
Who discovered the structure of the DNA molecule?
1953 – James Watson and Francis Crick propose a model for the structure of the DNA molecule. They publish the structure in the scientific journal Nature and suggest that the structure indicates DNA’s function.
How did James Watson contribute to the discovery of DNA?
At a conference in the spring of 1951 at the Zoological Station at Naples, Watson heard Wilkins talk on the molecular structure of DNA and saw his recent X-ray crystallographic photographs of DNA. He was hooked. James Watson and Francis Crick with their DNA model at the Cavendish Laboratories in 1953.
