Answer

Brief Explanations:

Rosalind Franklin's X - ray diffraction photo provided crucial evidence that DNA was a double - helix structure, which Watson and Crick used in their model. Chargaff's rule related to base - pair ratios, not ribose sugar. Levene's work was about nucleotide structure, not base - pair numbers per strand. Nirenberg and Matthaei's work was on the genetic code, not the basic structure of DNA being made of nucleotides.

Answer:

They used Franklin's photo to determine that DNA was a double helix.
