Untold Story of Double-Helix Discover (Rosalind Franklin) & Scientific Ethics
Rosalind+Franklin (power point)
Rosalind Franklin (25 July 1920 – 16 April 1958) was a British biophysicist and X-ray crystallographer who made critical contributions to the understanding of the fine molecular structures of DNA, RNA, viruses, coal, and graphite. Her DNA work achieved the most fame because DNA (deoxyribonucleic acid) plays an essential role in cell metabolism and genetics, and the discovery of its structure helped her co-workers understand how genetic information is passed from parents to children.
Franklin is best known for her work on the X-ray diffraction images of DNA which led to the discovery of the DNA double helix. Her data, according toFrancis Crick, were “the data we actually used” to formulate Crick and Watson‘s 1953 hypothesis regarding the structure of DNA.
