Question

Quizplus · Accepted Answer

Cells that do not divide are usually arrested in the G1 phase, which is the phase before DNA replication occurs. Once a cell enters S phase, it commits to dividing and will continue through the cell cycle unless something goes wrong. However, cells can also be arrested in other phases for various reasons such as DNA damage (G2/M checkpoint) or spindle assembly issues (prophase/metaphase checkpoint).
