Mcm in replication
WebThe loading of MCM complexes to origins of replication licenses these origins for activation by replication firing factors during the S phase ( 43 ). The normal cycling of shMcm6 cells ( 42) implied that the act of DNA replication was unlikely to be a causal factor in driving Myc-Igh translocations. Web5 jan. 2024 · Replication licensing in eukaryotes begins with the recruitment of two minichromosome maintenance (MCM) 2–7 complexes onto duplex DNA by the origin recognition complex (ORC) in an ATP-dependent manner. 1,2 The two hexameric MCM rings are loaded one at a time into a head-to-head double hexamer (DH) configuration …
