WebMay 9, 2024 · In any DNA sample, there are four bases that pair in only one way: adenine and thymine, guanine and cytosine. They total 100 percent of the sample. Chargaff's rule states that the concentration for each base in a base pair is always equal to its mate, so the concentration of adenine equals the concentration of thymine, for example.
