The Discovery of the DNA Structure
By 1950 Erwin Chargaff's changed the thinking about DNA by analyzing the DNA of several different organisms. Chargaff found that the same four bases are found in the DNA of all organisms, but the proportion of the four bases differs somewhat from organism to organism. These A = T and C = G relationships became known as Chargaff's rules.
Erwin Chargaff's Work
I conclude that DNA, the ratios of adenine (A) thymine (T) and guanine (G) to cytosine (C) are equal
Franklin and Wilkins Work
We founded out that from the image, DNA was helical.
At King's College in London, Rosalind Franklin and Maurice Wilkins were studying DNA. Wilkins and Franklin used X-ray diffraction as their main tool -- beaming X-rays through the molecule yielded a shadow picture of the molecule's structure, by how the X-rays bounced off its component parts.
Watsons and Cricks Work
We both used our findings in their own research. In April 1953, we published the news of their discovery, a molecular structure of DNA based on all its known features the double helix.
Watson and Crick worked together on studying the structure of DNA (deoxyribonucleic acid), the molecule that contains the hereditary information for cells. At that time Maurice Wilkins and Rosalind Franklin, both working at King's College, London, were using X-ray diffraction to study DNA.
