· 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 Owing to the “lagging” nature the lagging strand generally contains a longer stretch of ssDNA that is coated by single-stranded binding proteins which stabilizes ssDNA templates by preventing secondary structure formation or other transactions at the exposed ssDNA In eukaryotes ssDNA

PDF The DNA replication fork in eukaryotic cells
Initiation of eukaryotic DNA replication is the first stage of DNA synthesis where the DNA double helix is unwound and an initial priming event by DNA polymerase α occurs on the leading strand, The priming event on the lagging strand establishes a replication fork, Priming of the DNA helix consists of synthesis of an RNA primer to allow DNA synthesis by DNA polymerase α, Priming occurs once at the origin on the leading …

Eukaryotic DNA replication
The fundamental mechanisms that operate at the eukaryotic DNA replication fork are now quite well known and are discussed here Because the replication of DNA in eukaryotic cells must be coupled to DNA repair and assembly of the DNA into chromatin, the replication fork proteins play prominent roles in
eukaryotic replication fork three distinct replicative polymerase complexes contribute to canonical DNA replication: D G and H, These three polymerases are essential for viability of the cell [10±13],

Eukaryotic DNA Replication Fork
The DNA replication process can be heavily perturbed by several different conditions of genotoxic stress particularly relevant for cancer onset and therapy The combination of psoralen crosslinking and electron microscopy has proven instrumental to reveal the fine architecture of in vivo DNA replication intermediates and to uncover their remodeling upon specific conditions of genotoxic stress The replication structures are …
