What is the job DNA helicase?

DNA helicase is an essential enzyme involved in DNA replication and repair. Its primary function is to unwind the double-stranded DNA helix by breaking the hydrogen bonds between the nucleotide bases, creating two single strands that serve as templates for replication. This unwinding allows other enzymes, such as DNA polymerase, to synthesize new DNA strands. Overall, helicases play a crucial role in ensuring accurate and efficient DNA replication.
