Answer: 3′‑AGGTACTCAACT‑5′
Explanation: Knowing that the two strands are antiparallel and that T base pairs with A, while C base pairs with G, the sequence of the complementary strand will be 3′‑AGGTACTCAACT‑5′ (can also be written as TCAACTCATGGA). A segment of one strand from a DNA molecule has the sequence 5′‑CCAGTGAATTGCCTAT‑3′.
