Editing G2 phase (section)

== Homologous recombinational repair ==

During mitotic [[S phase]], [[DNA replication]] produces two nearly identical [[sister chromatids]].  DNA double-strand breaks that arise after replication has progressed or during the G2 phase can be [[DNA repair|repaired]] before cell division occurs (M-phase of the [[cell cycle]]).  Thus, during the G2 phase, double-strand breaks in one sister chromatid may be repaired by [[homologous recombination]]al repair using the other intact sister chromatid as template.<ref>{{cite journal | vauthors = Burgoyne PS, Mahadevaiah SK, Turner JM | title = The management of DNA double-strand breaks in mitotic G2, and in mammalian meiosis viewed from a mitotic G2 perspective | journal = BioEssays | volume = 29 | issue = 10 | pages = 974–86 | date = October 2007 | pmid = 17876782 | doi = 10.1002/bies.20639 | s2cid = 36778078 }}</ref>
