World Scientific, 2016. Lived 1905 – 2002. Erwin Chargaff's research paved the way for the discoveries of DNA's structure and its method of replication. His observation that DNA varies from species to species made it highly credible that DNA was genetic material.
His two main discoveries, (i) that in any double-stranded DNA the number of guanine units equals thenumber of cytosine units and the number of adenine units equals the number ofthymine units and (ii) that the composition of DNA varies from one species toanother, are now known as Chargaff's Rules.
