A. Eukaryotic cells store their genetic information in chromosomes made of DNA. This DNA is copied during interphase of the cell cycle. Replication is semiconservative, meaning one strand of the replicated DNA would be from the original molecule and one would be new. The parental strands serve as templates for the new strands. Replication can begin when helicase breaks the hydrogen bonds responsible for holding the two complementary strands together, ultimately causing the molecule to unwind. To ward against re-bonding of the strands, binding proteins stabilize each of the strands. The leading strand is synthesized by DNA polymerase at the replications origin from the 5’ to 3’ end continuously. The lagging strand is synthesized with
