The scientist famous for her research on the behavior of DNA is Rosalind Franklin. Her work at King’s College London involved using X-ray diffraction techniques to capture images of DNA. Franklin's famous photograph, known as Photo 51, was critical in revealing the helical structure of DNA, although her contributions were not fully recognized during her lifetime. Later, her research helped pave the way for advancements in genetics and molecular biology, emphasizing the importance of honoring scientific pioneers for their contributions.
