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.
However, DNA does not unzip entirely. It unzips in a small area called a replication fork, which then moves down the entire length of the molecule. Let's look at the details: 1  An enzyme called DNA gyrase makes a nick in the double helix and each side separates. 2  An enzyme called helicase unwinds the double-stranded DNA. 3  Several small proteins called single strand binding proteins (SSB) temporarily bind to each side and keep them separated.
