اسلاید 7: 7 Determining the 3-dimmensional structure of DNA1947: William Ashbury begins studying DNA structure using X-ray diffraction.1951–1953: Rosalind Franklin, working in Maurice Wilkins’ lab, obtains higher resolution pictures of DNA structure using X-ray diffraction techniques. discovered that DNA is helical and the molecule has a diameter of 2nm and makes a complete turn of the helix every 3.4 nm.1953: Watson and Crick propose the model of DNA structure. Deduced the structure of DNA using evidence from Chargaff, Franklin, and others. Proposed a double helix structure
