Describe the discoveries of Erwin Chargaff Rosalind Franklin and James Watson and Francis Crick?

Answer 1

Chargaff has Chargaff's rule named after him. That is that the number of A=T and the number of G=C in DNA.Franklin discovered the diffraction patterns of DNA. Watson and Crick put it all together, surmising that DNA is a double helix, with about 10 nucleotide base pairs per turn, and a major gap and a minor gap. They made a wire model.

Answer 2

Erwin Chargaff discovered the base pairing rules in DNA, which state that adenine pairs with thymine and cytosine pairs with guanine. Rosalind Franklin used X-ray diffraction to capture images of DNA's structure, providing key data for understanding its helical shape. James Watson and Francis Crick used Chargaff's and Franklin's work to propose the double helix structure of DNA, which earned them the Nobel Prize in Physiology or Medicine in 1962.
