A-T and C-G.

Adenine (A) pairs with thymine (T) via two hydrogen bonds, and cytosine (C) pairs with guanine (G) via three hydrogen bonds. This complementary pairing (Chargaff’s rule) is what holds the two antiparallel DNA strands together. In RNA, uracil (U) replaces thymine and pairs with adenine (A).
