Who amongst the following scientist had no contribution in the development of the double helix model for the structure of DN A?
|
|
Rosalind Franklin
|
|
|
Maurice Wilkins
|
|
|
Erwin Chargaff
|
|
|
Meselson and Stahl
|
Explanation:
Detailed explanation-1: -Final answer:d. Meselson and Stahl.
Detailed explanation-2: -So, the correct answer is ‘Meselson and Stahl’.
Detailed explanation-3: -Complete answer: Rosalind Franklin alongside Maurice Wilkins delivered the X-beam diffraction information of DNA and Erwin Chargaff proposed through cautious experimentation two guidelines that helped lead to the revelation of the twofold helix structure of DNA called the Chargaff rules.
Detailed explanation-4: -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.
