Draw a figure of one double stranded DNA molecule that has initiated replication and produced two okazaki fragment in each lagging strand. The figure must include both template strands, all newly synthesized DNA molecules on both leading and lagging strands, all RNA primers, direction of chain growth for each fragment/strand indicated with arrowheads, direction of replication forks. Each molecule must be labeled with the origin of replication on both strands, leading and lagging strands labeled, template or newly synthesized, DNA or RNA, 5' and 3' ends.

Which of the following statements about DNA replication is FALSE? Primase synthesizes the primers. DNA polymerase is required to add new nucleotides to the growing ends of the DNA strands. DNA ligase joins the small DNA fragments of the lagging strand. Only one strand of the parent DNA serves as a template for a newly synthesized complementary strand.
