The biochemist who made significant contributions to the field of genetics is Rosalind Franklin. Franklin's pioneering work in X-ray crystallography led to the discovery of the DNA double helix structure. Her famous Photograph 51 provided crucial insights into the molecular structure of DNA, which were essential to the work of James Watson and Francis Crick, who were awarded the Nobel Prize for their contributions to understanding DNA. Despite her critical role in the discovery, Franklin's contributions were largely unrecognized during her lifetime. Today, she is celebrated as a key figure in molecular biology and genetics.
