See complementary base pairing.
The phenomenon, based on chemical complementarity, whereby adenine (A) binds to uracil (U) or thymine (T), and guanine (G) to cytosine (C), in nucleic acids.
The pairing of specific nitrogenous bases between complementary strands of DNA. For example, adenine is always paired with thymine and guanine with cytosine.
