Question

Quizplus · Accepted Answer

Erwin Chargaff discovered that the amount of adenine (A) and thymine (T) in DNA is roughly equal, as is the amount of guanine (G) and cytosine (C), but the ratio of (A+T) to (G+C) varies between species. This finding, known as Chargaff's rules, was crucial for the understanding of DNA structure and its specificity.
