Detailed explanation-1: -If the cell fails to pass the checkpoint it can enter the G0 phase and become quiescent. The G2 phase follows the S phase and ends with the G2 checkpoint. This checkpoint determines if the cell will enter mitosis, the M phase.
Detailed explanation-2: -If the cell cycle checkpoints fail, cells that are not replicating correctly will be allowed to continue to grow and multiply. This is dangerous because the cell cycle mutations that are causing the failure can be passed on through the cell lineage.
Detailed explanation-3: -Disruption of normal regulation of the cell cycle can lead to diseases such as cancer. When the cell cycle proceeds without control, cells can divide without order and accumulate genetic errors that can lead to a cancerous tumor .
Detailed explanation-4: -Answer and Explanation: The correct answer choice is C. The nucleus replicates. Replication of the nucleus does not happen during interphase.
