Final answer:
Helicase unwinds the double-stranded DNA molecule in DNA replication, playing a vital role in the accurate synthesis of new DNA strands.
Explanation:
Helicase plays a crucial role in DNA replication by unwinding the double-stranded DNA molecule. It uses energy from ATP hydrolysis to separate the DNA strands, creating replication forks for the synthesis of new DNA strands.
Additionally, helicase helps prevent over-winding and supercoiling of DNA, ensuring the accurate replication of genetic information. Its function in opening up the DNA helix is essential for the initiation of the replication process.
