From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Because of its orientation, replication of the laggingstrand is more complicated than that of the leading strand. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Consider the following: the helicase continuously unwinds the parental duplex, but the laggingstrand must be polymerised in the opposite direction. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Primase also acts as a halting mechanism to prevent the leading strand from outpacing the lagging strand by halting the progression of the replication fork. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. On the leading strand this route is continuous, but on the laggingstrand it is discontinuous. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The laggingstrand is synthesized in short, separated segments. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. When this is complete, a single nick on the leading strand and several nicks on the laggingstrand can be found. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Electron microscopy studies indicate that nucleosome loading on the laggingstrand occurs very close to the site of synthesis. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Since replication occurs in opposite directions at opposite ends of parent chromosomes, each strand is a laggingstrand at one end. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The priming event on the laggingstrand establishes a replication fork. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. At this point, the laggingstrand replicative polymerase associates with the clamp and primer in order to start polymerisation. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. There is a richness of guanine over cytosine and thymine over adenine in the leading strand and vice versa for the laggingstrand. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. During laggingstrand synthesis, the replicative polymerase sends the laggingstrand back toward the replication fork. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Furthermore, the time used for replication between the two strands varies and may lead to asymmetric mutational pressure between leading and laggingstrand. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This makes the speed of laggingstrand synthesis much lower than that of the leading strand.
