E)determining the covalent bonding angles within DNA nucleotides.

Question

Quizplus · Accepted Answer

Rosalind Franklin's research using X-ray crystallography provided critical insights into the structure of DNA, including the fact that it exists in the form of a double helix and the dimensions of its backbone and base pairings. This information was essential to the discovery of the chemical composition of DNA, but it did not directly establish it. Similarly, while Franklin's work contributed to the understanding of the physical and chemical features of nucleotides, it did not determine their sequence or covalent bonding angles within DNA.
