WebApr 5, 2012 · Helicase is the enzyme that splits the double helix and unwinds this helix so that DNA polymerase can do it's job of running the leading and lagging strands of DNA in … WebSinglestrand binding proteins attach to each strand of the uncoiled DNA to keep them separate. As helicase unwinds the DNA, it forces the double-helix in front of it to twist. A group of enzymes, called topoisomerases, break and rejoin the double helix, allowing the twists to unravel and preventing the formation of knots.
