If one strand of DNA has the base sequence ATGGCT, the complementary strand would contain?

Explanation:
Base pairing rules drive the answer: adenine pairs with thymine, and guanine pairs with cytosine. To get the complementary strand, replace each base with its partner: A→T, T→A, G→C, G→C, C→G, T→A. Applying this to ATGGCT yields TACCGA. So the complementary strand would contain TACCGA. Other sequences don’t follow these pairing rules, so they aren’t correct representations of the complementary strand.
