DNA helicase is the enzyme that unwinds the DNA double helix by breaking the hydrogen bonds down the center of the strand. It begins at a site called the origin of replication, and it creates a replication fork by separating the two sides of the parental DNA.
DNA polymerase III (not DNA polymerase) is an enzyme that works in association with other enzymes during the replication of a DNA molecule.DNA replication begins when the enzyme, known as helicase unwinds a DNA strand. Helicase unwinds a DNA strand, thus, in the process, separating the two DNA templates.The result of the unwinding of the DNA molecule is the formation of a replication bubble. Once a DNA molecule is unwound, it is not stable.NA replication begins when the enzyme, known as helicase unwinds a DNA strand.
