Discover how DNA helicase creates a replication fork to unwind the complicated DNA molecule and allow daughter strands to form on the parental template. The Semi-Conservative Model This model states that one parental strand of DNA is conserved in each new daughter molecule.
DNA helicase is an enzyme that unwinds the DNA double helix by breaking the hydrogen bonds between the complementary bases. It's easy to remember the name because it has part of the word helix in it. You can imagine it sort of as a wedge that forces apart the two strands, just like the slider on a zipper wedges apart the two long rows of teeth.
