Question

Rosalind franklin used x-ray diffraction to study wet dna. her data were used by james watson and francis crick to determine the structure of dna. what did her data suggest about the structure of dna?

Answer 1

Her data suggested that DNA is a helical structure that has two strands attached in the middle by the phosphate bases. That was the necessary information, needed to complete an accurate model of the structure of DNA. She also was the first one to announce that the phosphate units are located in the external part of the DNA and that the amount of water found in the molecule is in accordance with other parts of it.
