The phrase 'enzymes unzip a molecule of DNA' describes which action?

Explanation:
Unzipping DNA means separating the two strands by breaking the hydrogen bonds between complementary base pairs. Enzymes like helicase use energy to unwind the double helix, creating exposed templates for processes such as replication or transcription. This action is about strand separation, not the synthesis of a new strand, nor protein synthesis, nor breaking down the DNA. So the description best fits unzipping DNA.
