Chargaff's rules are crucial principles in molecular biology that describe the base composition of DNA. Proposed by biochemist Erwin Chargaff in the 1950s, they can be summarized as follows: 1. **Base Pairing Rules**: In any given DNA molecule, the amounts of adenine (A) are equal to the amounts of thymine (T), and the amounts of guanine (G) are equal to the amounts of cytosine (C).
