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.
Select Unzip to divide the molecule. Selecting the Unzip button causes the DNA molecule to split lengthwise. In a real cell, the molecule unwinds from spools made of protein, then untwists. (Here the molecule is already unwound and untwisted.) The DNA now resembles a ladder. Enzymes, special kinds of proteins, move up the ladder, breaking the rungs.
