Quizplus · Accepted Answer

Enzymes that break hydrogen bonds are required to separate the two DNA strands during replication. In the diagram, this step is labeled as Step 1 and the molecule involved is an enzyme (not a specific molecule) that breaks the hydrogen bonds between the complementary base pairs. Therefore, the best choice is A)1.
