Helicase is an enzyme that plays a crucial role in DNA replication by breaking hydrogen bonds and separating the two strands of DNA, allowing them to be used as templates for the creation of new DNA strands.

Summarized this

Helicase is an enzyme that helps in DNA replication by separating the two strands of DNA, making them available for the synthesis of new DNA strands.

Helicase is an enzyme that is vital for DNA replication. It functions by breaking the hydrogen bonds between the DNA strands, which enables the separation of the double helix. This separation allows each strand to serve as a template for the synthesis of new DNA strands during replication.
