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.
It is required for DNA replication because the enzymes that catalyze this process, DNA polymerases, can only add new nucleotides to an existing strand of DNA. The polymerase starts replication at the 3'-end of the primer, and copies the opposite strand. In most cases of natural DNA replication, the primer for DNA synthesis and replication is a short strand of RNA. DNA primase DNA primase is an enzyme involved in the replication of DNA.
