Does Dna Polymerase Unwinds the Double Helix?

DNA helicase unwinds the double helix, separating the two strands so they may be replicated by DNA polymerase.

What unwinds the double helix?

Helicase (yellow) unwinds the double helix.

What unzips unwinds the double helix?

DNA replication begins when an enzyme called helicase unwinds, and unzips the DNA molecule.
