There are several enzymes that 'unzip' DNA. These enzymes are collectively known as DNA helicases. DNA helicases are helix-destabilizing enzymes that bind to DNA at the origin of replication and break hydrogen bonds, thereby separating the two strands.. Solomon, Eldra P., Linda R. Berg, and Diana W. Martin. Biology. 8th ed. Belmont, CA: Thomson Brooks/Cole, 2008.
Lesson Summary. In summary, we have covered what DNA polymerase is and what it does. DNA polymerase is an enzyme that synthesizes new copies of DNA. It carries out this function after DNA helicase has unzipped the DNA thereby creating two single strands of DNA that can be used as templates.he result of DNA polymerase function is two copies of DNA that contain one original and one newly synthesized strand of DNA.
