Checkpoints play a key role in keeping things organized during the cell cycle. However, they can run into some problems:

• Dysfunction: When checkpoints don’t work right, cells may start dividing without control. This can lead to cancer.
• Complexity: The complex signals that help control these checkpoints can get messed up.

Solutions:

• We need to boost research to understand how checkpoints really work.
• We should create targeted treatments that fix or work around these problems. This can help bring back proper control of the cell cycle.
