Question

Quizplus · Accepted Answer

The correct answer is A because the base sequence along a portion of one strand of a double helix is CTACACG, the corresponding sequence on the other strand is GATGTGC. This is because DNA is a double helix, and the two strands are complementary to each other. This means that the base sequence on one strand will determine the base sequence on the other strand. In this case, the base sequence on one strand is CTACACG, so the corresponding sequence on the other strand must be GATGTGC.
