MCQ - 497-1981

Question:

The partial sequence of a single DNA strand is shown. What will be the sequence of the complementary strand produced during DNA replication?

  1. 3’–ATGCTGAACT– 5’
  2. 5’–ATGCTGAACT– 3’
  3. 5’–CGTAGTCCAG– 3’
  4. 5’–ATGCTGAACT– 3’
  5. 5’–TACGACTTGA–3’

Correct Answer: E

Explanation:

The complementary base-pairing rule for DNA is that adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). DNA strands run antiparallel, so the complementary strand will be in the 5’-to-3’ direction. The complementary sequence is, therefore, 5’–TACGACTTGA–3’.
