  2. DNA replication - Wikipedia

    en.wikipedia.org/wiki/DNA_replication

    a: template, b: leading strand, c: lagging strand, d: replication fork, e: primer, f: Okazaki fragments Many enzymes are involved in the DNA replication fork. The replication fork is a structure that forms within the long helical DNA during DNA replication.

  3. GC skew - Wikipedia

    en.wikipedia.org/wiki/GC_skew

    This asymmetry is due to the formation of the replication fork and its division into nascent leading and lagging strands. The leading strand is synthesized continuously and in juxtapose to the leading strand; the lagging strand is replicated through short fragments of polynucleotide (Okazaki fragments) in a 5' to 3' direction. [6]

  4. Eukaryotic DNA replication - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_DNA_replication

    The discontinuous stretches of DNA replication products on the lagging strand are known as Okazaki fragments and are about 100 to 200 bases in length at eukaryotic replication forks. The lagging strand usually contains longer stretches of single-stranded DNA that is coated with single-stranded binding proteins, which help stabilize the single ...

  5. Rolling circle replication - Wikipedia

    en.wikipedia.org/wiki/Rolling_circle_replication

    As a summary, a typical DNA rolling circle replication has five steps: [2] Circular dsDNA will be "nicked". The 3' end is elongated using "unnicked" DNA as leading strand (template); 5' end is displaced. Displaced DNA is a lagging strand and is made double stranded via a series of Okazaki fragments. Replication of both "unnicked" and displaced ...

  6. Primer binding site - Wikipedia

    en.wikipedia.org/wiki/Primer_binding_site

    One of the new strands, the leading strand, moves in the 5' to 3' direction until it reaches the replication fork, allowing DNA polymerase to take the RNA primer and make a new complementary DNA strand to the template strand. The lagging strand moves away from the replication fork in the 3' to 5' direction and consists of small fragments called ...

  7. Okazaki fragments - Wikipedia

    en.wikipedia.org/wiki/Okazaki_fragments

    The leading strand is continuously synthesized and is elongated during this process to expose the template that is used for the lagging strand (Okazaki fragments). During the process of DNA replication, DNA and RNA primers are removed from the lagging strand of DNA to allow Okazaki fragments to bind to.

  8. Replisome - Wikipedia

    en.wikipedia.org/wiki/Replisome

    DNA is a duplex formed by two anti-parallel strands. Following Meselson-Stahl, the process of DNA replication is semi-conservative, whereby during replication the original DNA duplex is separated into two daughter strands (referred to as the leading and lagging strand templates). Each daughter strand becomes part of a new DNA duplex.

  9. Antiparallel (biochemistry) - Wikipedia

    en.wikipedia.org/wiki/Antiparallel_(biochemistry)

    The antiparallel structure of DNA is important in DNA replication because it replicates the leading strand one way and the lagging strand the other way. During DNA replication, the leading strand is replicated continuously whereas the lagging strand is replicated in segments known as Okazaki fragments.
