Checkpoints act like quality control stations during the cell cycle. They make sure everything is working well and can pause the process if something doesn't seem right. Here's how they work:
G1 Checkpoint: This checkpoint looks for any damage to the DNA and checks if there are enough nutrients. If everything isn’t okay, the cell can take a break or fix itself.
G2 Checkpoint: This one checks if the DNA was copied correctly and if the cell is ready for the next step, called mitosis.
M Checkpoint: During mitosis, this checkpoint watches the spindle fibers to make sure that the chromosomes are lined up properly.
These checkpoints help prevent mistakes, which can help stop problems like cancer!
