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.
