How did erwin chargaff discover dna
WebResearch to determine the structure of DNA took on an added urgency (although final confirmation of its central role was still to come, from experiments carried out by Alfred Hershey and Martha Chase in the US in the early 1950s). The Austrian chemist, Erwin Chargaff - for one - was deeply impressed by Avery’s work. WebInfo Erwin Chargaff found that in DNA, the ratios of adenine (A) to thymine (T) and guanine (G) to cytosine (C) are equal. This parity is obvious in the final DNA structure.
