WebJul 20, 2024 · Based on these breakpoint sequences, we propose a model of NAHR and breakage-fusion-bridge (BFB) cycles for the formation and resolution of complex CNVs in C. albicans . For example, to generate the Chr3L complex CNV, a DNA double-strand break (DSB) occurs (the exact location of the DSB is not known) between the telomere and the …

WebJul 25, 2014 · In the latter context, the multimer initiates a breakage-fusion-bridge (BFB) cycle that generates large HSRs . This cycle involves breakage at the plasmid repeat, followed by replication/end fusion resulting in generation of a dicentric chromosome and chromatin bridge during the anaphase. Breakage of the bridge at a point shifted from …
