Question

what is the role of helicase in dna replication? it glues the dna fragments together. it builds a new strand of dna. it unzips the dna by breaking hydrogen bonds. it initializes the replication process.

Explanation:

Helicase is an enzyme in DNA replication. It functions by breaking the hydrogen - bonds between the two strands of the double - helix DNA, thus 'unzipping' it to expose the single - stranded DNA templates for replication.

Answer:

"It unzips the DNA by breaking hydrogen bonds."
