(Recall that N = 1 copy of each chromosome per cell [haploid]; 2N = 2 copies [diploid].) WebJan 5, 2024 · How the checkpoint response is tailored to different phases of the cell cycle remains poorly understood. The S-phase checkpoint for example results in the slowing of replication, which in budding yeast occurs by Rad53-dependent inhibition of the initiation factors Sld3 and Dbf4. exterior inswing door threshold
