Chargaff discovered that in DNA the percentages of adenine and thymine were the same, and the percentages of cytosine and guanine are the same. This led to the idea of base-pairing between adenine and thymine, and cytosine and guanine.

Chargaff's rules showed that in DNA, the amount of adenine is equal to thymine and the amount of guanine is equal to cytosine. This helped Watson and Crick understand the complementary base pairing in DNA, leading to their proposal of the double helix structure.
