WebAnalysis of breakpoint regions suggested several different mechanisms, including nonhomologous end joining (NHEJ), nonallelic homologous recombination (NAHR), and replication fork stalling and template switching (FoSTeS). Yan et al. (2009) suggested that copy number variation can be a common mechanism for genetic diseases. WebThe last switching event restores a replicative DNA polymerase on the DNA template and reinitiates normal DNA synthesis. However, while the TLS is an easy, straightforward mechanism allowing lesion bypass and …
