It unwinds the DNA.

Explanation:

DNA is double stranded. Enzymes that are responsible for replication of DNA can only bind to a single strand of DNA.

Helicase is the enzyme that unwinds the DNA by breaking hydrogen bonds between the two strands. It forms the so called replication fork. Other proteins assist helicase to keep the strands apart as long as required for the replication process.
