The American biochemist Erwin Chargaff discovered that DNA is the primary constituent of the gene, thereby helping to create a new approach to the study of the Biology of heredity.
Basically chargoffs rule, of i all know, Thymine equals the Adenine, Cytosine equals the Guanine, and something else about the pyrmine. - nikkiYes, Nikki is close and she has the right idea. Erwin Chargraff, an American biochemist, had discovered that the percentages of guanine (G) and cytosine (C) bases are almost equal in any sample of DNA. But the same thing is true for the other nucleotides, adenine (A) and thymine (T). (A) = (T) and (G) = (C) became known as Chargraff's rules. - bradberrya
Those are Chargraff's Rules. You're wrong to think that adenine and thymine are the only pairs however because in RNA, adenine always pairs with uracil. Thymine is not in RNA. Adenine and Guanine are purines. Cytosine, thymine, and uracil are purimidines. Sources: My Science class and textbook Hope this helped!

Chargaff discovered that in DNA, there is a 1:1 ratio of adenine and thymine, and a 1:1 ratio of guanine and cytosine. This led to the rule that adenine always pairs with thymine and guanine always pairs with cytosine.
