WebWe recently proposed a DNA replication-based mechanism of fork stalling and template switching (FoSTeS) to explain the complex genomic rearrangements associated with a … WebJun 2, 2024 · This is based on a replication-based mechanism involving template-switching between sister chromatids. When a DNA replication fork encounters a replication block caused by different types of DNA damage, DNA synthesis may stall and a DNA end will then emerge.

WebNote that template switching can also occur after fork regression, as illustrated in Figure 4B. ( E) Incomplete nucleotide excision repair of the DNA lesion or cleavage of the fork by endonucleases may also lead to the formation of a one-ended DSB, which can be repaired by an HR-related process called break-induced replication. http://www.arnoldsdesign.com/Easy-To-Build-Tractor-Forks.html marilyn bowen facebook

They arise due to a change of single-stranded DNA template during replication, which is known as template switching, after replication fork stalling or breakage. Replication fork stalling can lead to the mechanism named Fork Stalling and Template Switching (FoSTeS) (Fig. 5 A). See more Most recurrent rearrangements are caused by a mechanism named Non-Allelic Homologous Recombination (NAHR) that occurs … See more Replication-based mechanisms have been proposed to explain complex rearrangements containing multiple breakpoints, insertions of DNA segments, and microhomology … See more The main pathway for repairing of two-ended double-strand breaks is the Non-Homologous End-Joining (NHEJ) mechanism [24, 46].
