Who first conducted the X-ray crystallography of DNA?
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.
Who proposed the X-ray diffraction data?
Max von Laue, in 1912, discovered that crystalline substances act as three-dimensional diffraction gratings for X-ray wavelengths similar to the spacing of planes in a crystal lattice.
What was Watson and Crick’s experiment?
Watson and Crick showed that each strand of the DNA molecule was a template for the other. During cell division the two strands separate and on each strand a new “other half” is built, just like the one before.

What did Franklin and Wilkins discover?
In 1962, James Watson, Francis Crick and Maurice Wilkins received the Nobel prize for the discovery of the structure of DNA. Notably absent from the podium was Rosalind Franklin, whose X-ray photographs of DNA contributed directly to the discovery of the double helix.

Did Rosalind Franklin know that DNA was a helix?
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 was Maurice Wilkins role in the discovery of DNA?
In 1962 Wilkins was awarded the Nobel Prize with Francis Crick and James Watson for his contribution to the elucidation of the structure of DNA. Wilkins had been involved in the formative x-ray diffraction work on DNA and was responsible for showing the first crystalline symmetrical patterns of DNA.
What did Erwin Chargaff discover?
Chargaff discovered regularities among the four chemical units of DNA known as bases, pointing directly to its role as the hereditary material of living organisms.
What did Rosalind Franklin discover?
Rosalind Franklin made a crucial contribution to the discovery of the double helix structure of DNA, but some would say she got a raw deal. Biographer Brenda Maddox called her the “Dark Lady of DNA,” based on a once disparaging reference to Franklin by one of her coworkers.
What did Maurice Wilkins discover?
Maurice Wilkins shared the Nobel Prize with Francis Crick and James Watson in 1962 for their joint discovery of the structure of DNA.
What did James Watson discover?
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 …

Who was Francis Crick?
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.
How did Wilkins and Franklin study 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.
