Torsional stress during DNA replication is released by DNA topoisomerases. In contrast to prokaryotes, DNA replication in eukaryotes not only has to create two identical daughter strands but also must conserve higher-order structures like chromatin....
In eukaryotes, the origin recognition complex (ORC) is essential for replication licensing. Here, the authors report that a short motif within the intrinsically disordered region of the yeast Orc2 subunit plays an important role in regulating the licensing process. ...
Eukaryotic chromosomes are much longer than bacterial ones and have multiple replication origins. Just as in prokaryotes, several proteins load onto the origin of replication in a specific order to control replication initiation in eukaryotes. In eukaryotes the cell cycle consists of a “rest” period...
If the action of telomerase in these cells can be inhibited by drugs during cancer therapy, then the cancerous cells could potentially be stopped from further division. Section Summary Replication in eukaryotes starts at multiple origins of replication. The mechanism is quite similar to that in ...
This process is called DNA replication and is essential to all forms of life. The molecular mechanisms are usually conserved within any of the three major kingdoms (Bacteria, Archaea, and Eukaryotes) but can widely differ among them. On the contrary, replicative strategies can be very diverse ...
DNA replication in eukaryotes is a conserved system that only allows for DNA replication to occur once throughout each cell cycle.Share Introduction In the course of DNA replication, a single strand of DNA duplicates itself several times. It is a type of biological polymerisation that occurs in ...
DNA replication in eukaryotes initiates at many origins distributed across each chromosome. Origins are bound by the origin recognition complex (ORC), which, with Cdc6 and Cdt1, recruits and loads the Mcm2-7 (MCM) helicase as an inactive double hexamer during G1 phase. The replisome assemble...

注:①“非编码损伤”(noncoding or replication-blocking lesions)是指对DNA复制构成明显阻碍的DNA损伤。那些对DNA复制没有明显阻碍但可导致点突变率显著提升的DNA损伤被称为“错码损伤”(miscoding lesions)。(15)本文在讨论TLS时,只涉及“非编码损伤”。 ②当遇到后随链模板上的DNA损伤时,复制叉会几乎没有停顿的...
The proteins of replication forks of eukaryotes and prokaryotes are also different, but the corresponding parallel relationship can be found, as summarized in the figure below. Fig. 13 Comparison of replication forks between prokaryotes and eukaryotes ...
