The double-stranded DNA molecule unwinds to expose its two complementary strands during DNA replication, which is a critical process for cell growth, repair, and reproduction. The leading DNA strand serves as a template for the lagging strand’s complementary partner’s continuous synthesis.
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.
Aug 8, 2018 · 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...
Apr 21, 2024 · During replication, one strand, which is complementary to the 3’ to 5’ parental DNA strand, is synthesized continuously toward the replication fork because polymerase can add nucleotides in this direction. This continuously synthesized strand is known as the leading strand.
On one strand, the replication process is continuous and fast; this newly formed daughter strand is called the leading strand. On the other strand, the replication process is discontinuous, relatively slower, and starts slightly later; this daughter strand is known as the lagging strand.
Leading strand formation: The strand that can be replicated on a continuous basis as helicase unwinds the DNA is called the leading strand. In figure 13c, there are two leading strands, one for each fork. For the left fork, the leading strand of DNA is being created from the bottom strand since the helicase is opening up 3’ to 5’ DNA for ...
