Checkpoints are super important for controlling the cell cycle.
Think of them as quality control stations. They make sure the cell is ready to move to the next stage. Let's break down how they work:
G1 Checkpoint: Before the cell copies its DNA, it checks for any damage and makes sure it’s the right size. If things aren’t right, the cell can stop or rest for a while.
G2 Checkpoint: After the cell has copied its DNA, it looks for mistakes in the new copies. This step makes sure everything is correct before the cell goes into the next stage called mitosis.
M Checkpoint: While the cell is in mitosis, this checkpoint checks that all the chromosomes are properly attached to the spindle. The spindle helps pull them apart when the cell divides.
These checkpoints help prevent mistakes during cell division, which keeps cell growth healthy!
