What was Rosalind Franklin’s role in the discovery of the structure of DNA?
|
|
She discovered that DNA is made of nucleotides
|
|
|
She carried out X-ray diffraction experiments leading to the determination that DNA is a double helix.
|
|
|
She carried out X-ray diffraction experiments and concluded that DNA strands run in opposite directions.
|
|
|
She produced the three-dimensional molecular model of DNA to show that it is a double helix.
|
Explanation:
Detailed explanation-1: -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.
