Question

read the article and use the information to answer the questions that follow. discovering the structure of dna explain how the discoveries by rosalind franklin helped watson and crick build an accurate model of dna.

Explanation:

Rosalind Franklin used X - ray crystallography to take high - quality images of DNA fibers. Her Photo 51 clearly showed the double - helix structure of DNA, including the spacing and angles between the components. This provided crucial structural information that Watson and Crick used to build their accurate model of the DNA double - helix.

Answer:

Rosalind Franklin's X - ray crystallography images, especially Photo 51, provided key structural details like spacing and angles that allowed Watson and Crick to build an accurate DNA model.
