The “leading strand” is synthesized continuously toward the replication fork as helicase unwinds the template double-stranded DNA. The “lagging strand” is synthesized in the direction away from the replication fork and away from the DNA helicase unwinds.
The lagging strand is the strand of new DNA whose direction of synthesis is opposite to the direction of the growing replication fork. Because of its orientation, replication of the lagging strand is more complicated as compared to that of the leading strand.
The major difference between a lagging and leading strand is that the lagging strand replicates discontinuously forming short fragments, whereas the leading strand replicates continuously. Find out more such differences between a lagging and leading strand, in the table below.
DNA replication of the leading and lagging strand. The helicase unzips the double-stranded DNA for replication, making a forked structure. The primase generates short strands of RNA that...
The main difference between leading and lagging strand is that the leading strand is the DNA strand, which grows continuously during DNA replication whereas lagging strand is the DNA strand, which grows discontinuously by forming short segments known as Okazaki fragments.
One strand is synthesized continuously in the direction of the replication fork; this is called the leading strand. The other strand is synthesized in a direction away from the replication fork, in short stretches of DNA known as Okazaki fragments. This strand is known as the lagging strand.
Leading strand is synthesised continuously. DNA polymerase adds nucleotides to the deoxyribose (3’) ended strand in a 5’ to 3’ direction. Lagging strand is synthesised in fragments.
Roles of DNA polymerase, primase, ligase, helicase and topoisomerase in DNA replication. An explanation of leading and lagging strands. Watch the next lesson:...
Two DNA polymerase molecules work at the fork, one on the leading strand and one on the lagging strand. The DNA helix is opened by a DNA polymerase molecule clamped on the leading strand, acting in concert with one or more DNA helicase molecules running along the strands in front of it.
Understanding the mechanics behind it helps elucidate how genetic information is accurately passed from one generation to the next. This article delves into the intricacies of DNA synthesis, particularly focusing on the differences between leading and lagging strands.
