Answer:
The role of the helicase enzyme in DNA replication is to separate DNA from double strands into single strands.
Step-by-step explanation:
Helicases are biological or natural macromolecules that accelerate chemical reactions (enzymes). These enzymes use the energy of the hydrolysis of a nucleoside triphosphate to break the hydrogen bonds that hold the strands of the double-stranded DNA together, thus being essential for the progress of the replication fork. The job of the helicase is to allow the advance of the replication forks by "unrolling" the DNA (breaking the hydrogen bonds between the nitrogen base pairs). Once the enzymes bind to the DNA they move in a specific direction, coupling their movement with the hydrolysis of the ATP and the unwinding of the chain.
