DNA molecule is the main carrier of biological genetic information, so its replication is of great significance in the life process. This review will focus on the process of DNA replication in detail, including its chemical structure, catalytic principle, various enzymes involved, spatial conformation...

For example, since human cells have 23 different types of chromosomes, each cell receives 46 chromosomes, and after DNA replication, each cell has 92 chromatids. When a human somatic cell undergoes mitosis, or cell division, the sister chromatids separate, resulting in two daughter cells with ...

Replicon Theory, Regulation of DNA Replication and Genomic Instability Benjamin D.Pope,David M.Gilbert, inJournal of Molecular Biology, 2013 Highlights • DNA replication in mammals must accommodate large-scale chromosome architecture. • Dynamics ofDNA replication timingreveal various levels of chromos...
Eukaryotic DNA replication refers to the process by which eukaryotic cells duplicate their DNA, involving the binding of the origin recognition complex (ORC) to replication origins, the formation of pre-replicative complexes (pre-RCs), and the initiation of DNA replication by helicase activity. This...
double-strand break DNAsingle-stranded DNAMaintenance of genome stability in response to DNA damage is essential for cell survival. DNA damage occurs following external insults such as ultraviolet light and ionizing radiations or as a consequence of DNA replication or physiological DNA rearrangements. ...
