Question

the enzyme that unzips the dna to prepare for replication
ligase
replicase
polymerase
helicase

Explanation:

• Ligase seals DNA strand breaks.
• Replicase aids in viral genome replication, not DNA unzipping.
• Polymerase synthesizes new DNA strands.
• Helicase breaks hydrogen bonds between DNA base pairs, unzipping the double helix for replication.

Answer:

helicase
