What was a key finding of Rosalind Franklin in her research?

Rosalind Franklin made significant contributions to our understanding of the molecular structures of DNA, particularly through her work with X-ray diffraction images. Her famous Photograph 51 provided critical evidence for the double helix structure of DNA. This image showed the characteristic X-shaped pattern indicative of a helical structure, which was crucial for the later identification of DNA's double helix by James Watson and Francis Crick. Her detailed analysis of these images, along with her expertise in crystallography, laid the groundwork for deciphering the structure of DNA, confirming its role as the carrier of genetic information. This monumental finding has had lasting implications in genetics, biology, and many related fields.
