The unzipping enzyme
WebEnzymes known as helicases unwind the double helix by breaking the hydrogen bonds between complementary base pairs, while other proteins keep the single strands from rejoining. The... WebWhat is the unzipping enzyme? Helicases are enzymes involved in unzipping of the double stranded DNA molecule at beginning of DNA replication. They do so by binding at DNA sequences called origins on DNA molecule then they break the hydrogen bonds between complementary base pairs causing the two strands of DNA molecule to unzip.
