WebAug 22, 2024 · Why is Chargaff’s rule important to DNA? 1 Answer. Chargaff’s rule states that DNA from any cell of any organism has a 1:1 ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine, a purine base, is equal to cytosine, a pyrimidine base; and the amount of adenine, a purine base, is equal to thymine, a ... WebApr 24, 2024 · 1944-1950 — Erwin Chargaff discovered that DNA is responsible for heredity and that it varies between species. His discoveries, known as Chargaff’s Rules, proved that guanine and cytosine units, as well as adenine and thymine units, were the same in double-stranded DNA, and he also discovered that DNA varies among species.
