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.
Lesson Summary. Let's review what we've learned so far. 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.esson Summary. Let's review what we've learned so far.
