What method did Rosalind Franklin use?

Answer 1

Rosalind Franklin was a British biophysicist. She largely contributed to the understanding of the fine molecular structures of DNA, RNA, viruses, coal, and graphite by using the method of X-ray crystallography..

Answer 2

Rosalind Franklin used X-ray crystallography to study the structure of DNA. This technique involves directing X-rays at a crystal of a molecule and analyzing the resulting diffraction pattern to determine the molecule's spatial arrangement. Franklin's work was critical in providing important insights into the helical structure of DNA.
