Question

question 4
the enzyme____unzips and unwinds the dna molecule
o helicase
o primase
o dna polymerase
o dna ligase

Explanation:

Helicase is an enzyme that plays a crucial role in DNA replication. It specifically functions to unzip and unwind the double - stranded DNA molecule by breaking the hydrogen bonds between the base pairs. DNA ligase joins DNA fragments, DNA polymerase synthesizes new DNA strands, and primase synthesizes RNA primers.

Answer:

helicase
