What did X-ray diffraction photographs by Wilkins and Franklin suggest?
suggested that DNA and RNA are the same molecules.
Who conducted the X-ray diffraction studies that were key to the discovery of the structure of DNA?
Rosalind Franklin
Rosalind Franklin used X-ray diffraction to determine the structure of DNA molecules. One of her best X-ray pictures is numbered Photo 51 and is shown in Fig.

What was Maurice Wilkins role in the discovery of 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 happened to the ribosome after translation?
During translation, the two subunits come together around a mRNA molecule, forming a complete ribosome. The ribosome moves forward on the mRNA, codon by codon, as it is read and translated into a polypeptide (protein chain). Then, once translation is finished, the two pieces come apart again and can be reused.
What did Franklin and Wilkins discover?
Abstract. 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.
What is the pattern in Franklin’s famous photo?
After exposing the DNA fibers to X-rays for a total of sixty-two hours, Franklin collected the resulting diffraction pattern and labeled it Number 51 that became Photo 51. Photo 51 presents a clear diffraction pattern for B-Form DNA. The outermost edge of the diffraction pattern consists of a black diamond shape.
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.
