The function of Helicase in the process of DNA replication is to untwist the double helix and separating the two DNA strands. This action of helicase creates the replication forks and replication bubbles where the process of replication is initiated.

It may also function in other cellular processes where the double-stranded DNA must be separated, including transcription and repair. <span />
