Answer:
The cell cycle is mainly regulated with the help of three checkpoints: G₁ checkpoint, G₂ checkpoint, and M checkpoint.
G₁ checkpoint checks for
- DNA (deoxyribonucleic acid) damage.
Hence, it can be correctly matched with checks for cell size and DNA damage.
Only after passing through this check point the cell enters the S or synthesis phase where the DNA content is doubled.
The G₂ checkpoint is present between G₂ phase and M phase. It checks the cell for its protein reserves as well as if the DNA has replicated accurately or not.
If cell passes this checkpoint then it enters into the M phase.
Hence, it can be correctly matched with checks whether DNA has doubled and repairs it if damaged
Lastly, the M checkpoint checks if spindle microtubules are properly attached to the centromeres of all the chromosomes.
This checkpoint allows the progression from metaphase to anaphase.
Hence, it can be correctly matched with microtubules have attached to the centromeres of the chromosomes.
