Which enzyme breaks apart the DNA strand according to the material?

Explanation:
During DNA replication, the double helix must be opened so enzymes can read the genetic code. The enzyme that doing this is helicase. It uses energy from ATP to break the hydrogen bonds holding the base pairs together, creating a replication fork and providing single-stranded templates for synthesis. RNA polymerase makes RNA from a DNA template, not used to separate the strands. DNA polymerase copies DNA once the strands are separated, but it does not unwind the helix itself. DNA ligase seals nicks after synthesis, not involved in strand separation.
