WebApr 1, 1997 · Cell cycle checkpoints sense flaws in critical events such as DNA replication and chromosome segregation . When checkpoints are activated, for example by underreplicated or damaged DNA, signals are relayed to the cell cycle-progression machinery. These signals cause a delay in cycle progression, until the danger of … WebThe cell cycle is controlled at three checkpoints. The integrity of the DNA is assessed at the G 1 checkpoint. Proper chromosome duplication is assessed at the G 2 checkpoint. Attachment of each kinetochore to a spindle fiber is assessed at the M checkpoint.
