Answer: Helicase

Explanation: Replication is a process of making two identical copies of DNA from a double-stranded DNA. This process is catalyzed by an enzyme called DNA polymerase. Before DNA polymerase begins the synthesis of the new strands, helicase will unwind or unzip the double-stranded DNA. Helicase is the enzyme that unzips or unwinds the double-stranded DNA helix during replication. Helicase separates the two strands by moving along the DNA using chemical energy from ATP. The separated strands serve as templates for the synthesis of new DNA strand.
