Lagging strand
DNA polymerase enzyme is responsible for the polymerization activity of DNA. On the leading strand DNA synthesis is continuous. But on the lagging strand it is discontinuous. It takes place with the formation of many small fragments of DNA. These fragments are called as okazaki fragments. When the process of replication is completed, this fragments are joined together by DNA ligase enzyme.
Please rate high.

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...
