Helicase: The Molecular Machine That Unzips DNA
Helicase: The Molecular Machine That Unzips DNA Why in the News ? A recent Nature Communications study by U.K. scientists revealed a molecular “safety catch” that regulates the timing of DNA replication. The finding improves understanding of how cells prevent premature DNA copying and maintain genomic stability during cell division. Role of Helicase in DNA …
