Outra informação chave relacionada à estrutura de DNA veio do bioquímico austríaco Erwin Chagaff. Chargaff analisou o DNA de diferentes espécies, determinando sua composição de bases A, T, C e G. Ele fez várias observações fundamentais:
1 de mar. de 2013 · Erwin Chargaff foi um bioquímico que descobriu a composição e a simetria dos nucleotídeos do DNA, essenciais para Watson e Crick montarem o modelo de DNA. Saiba mais sobre sua contribuição e os outros cientistas envolvidos na história da genética.
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.
