Confidence votes 106. The role that enzymes plays in DNA replication is that the enzyme helicase breaks hydrogen bonds between the complementary bases, and the chains separate.
DNA primase, DNA polymerase and helicases are the main enzymes involved in DNA replication. The original DNA structure is unwound by helicases, at the origin of replication and each original single-stranded DNA molecule is used as a template.Single-stranded binding proteins then bind to the template to prevent degradation of the original DNA molecule.he first step of DNA replication is the unwinding of the double helix at specific points, called origins of replication. There may be hundreds or thousands of origins of replication in our DNA; however, there is usually only one in bacteria.
