Helicases are often used to separate strands of a DNA double helix or a self-annealed RNA molecule using the energy from ATP hydrolysis.
A DNA helicase is an<em> enzyme </em>that functions by melting the hydrogen bonds that hold the DNA into the double helix structure. The area of the DNA where the DNA helicase has unzipped the DNA is known as a replication fork.
