what is the function of dna helicases
Think of two separate pieces that are held together by hydrogen bonds. The job of Helicase is to unzip the DNA strand â¦ by breaking the hydrogen bonds that hold them together, and it does this by moving along the strand of DNA, very much like on an actual zipper. Because of this type of movement, helicase is a type of `motor protein.`. 1 person found this useful. Shelley Morton.
