How Cell Checkpoints Work

Cell checkpoints are essentially internal gates that monitor and regulate cellular processes, ensuring that cells function properly and maintain their integrity. These checkpoints can be thought of as "stop signs" that prevent cells from entering dangerous or unauthorized pathways. When a cell detects damage or aberrations, the checkpoint mechanism springs into action, halting cell division and allowing for repair or elimination of the affected cell.
