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.
New nucleotides, floating free in the cell, can then hook up with complementary nucleotides along each strand. Gradually the unzipping proceeds, and the new strands continue to grow until one DNA molecule becomes two identical DNA molecules. A cell copies all of its DNA in this fashion each time it divides.
