In DNA, adenine is the complementary base for _____, and cytosine is the complement for ______.

  • A.guanine, thymine
  • B.uracil, guanine
  • C.thymine, guanine
  • D.thymine, uracil

Answer: C

Correct answer: thymine, guanine

The pairing is fixed by hydrogen bonding: A with T through two bonds, and C with G through three. Uracil replaces thymine in RNA, so it plays no part in DNA.
