Detailed explanation-1: -Certain proteins bind to the origin of replication while an enzyme called helicase unwinds and opens up the DNA helix.
Detailed explanation-2: -During replication, the helicase has to unwind a long stretch of DNA, and that requires the helicase to couple strand-separation activity to translocation. The mechanisms of these critical processes of the helicase reaction are largely unknown.
Detailed explanation-3: -Helicases are essential enzymes involved in all aspects of nucleic acid metabolism including DNA replication, repair, recombination, transcription, ribosome biogenesis and RNA processing, translation, and decay.
Detailed explanation-4: -DNA helicase is an enzyme that unwinds the DNA double helix by breaking the hydrogen bonds between the complementary bases.
