Checkpoints in the cell cycle are like safety checks before a cell divides. They make sure everything is okay before moving on to the next step. Here’s a simple breakdown of how they work:
G1 Checkpoint: This check looks for any damage to the cell’s DNA and checks if the cell is the right size. If something's wrong, the cell can pause or even destroy itself.
G2 Checkpoint: This step makes sure that the DNA was copied correctly. If there are mistakes, the cell has a chance to fix them.
M Checkpoint: This check looks at how the chromosomes are lined up. If they aren’t in the right place, the cell won’t move forward.
These checkpoints are very important. They help stop mistakes that could cause serious issues, like cancer!
