What triggers cell cycle checkpoints?

At its core, the cell cycle is a series of events that allow a cell to grow, replicate its DNA, and divide into two daughter cells. This process is orchestrated by a complex interplay of molecular signals and checkpoints that ensure the process unfolds correctly. The critical cell cycle checkpoints serve as crucial gatekeepers, halting the cell cycle to allow for error correction or programmed cell death (apoptosis) if the cell's integrity is compromised.
