Final answer:
The three different checkpoints in interphase during eukaryotic cell division are the G1 checkpoint, the G2 checkpoint, and the M checkpoint.
Step-by-step explanation:
During interphase in eukaryotic cell division, there are three different checkpoints that help regulate the cell cycle. The first checkpoint is called the G1 checkpoint and it occurs near the end of the G1 phase. At this checkpoint, the integrity of the DNA is assessed to ensure it is undamaged and ready for replication.
The second checkpoint is the G2 checkpoint which occurs near the end of the G2 phase. At this checkpoint, the proper duplication of the chromosomes is assessed to ensure there are no errors or abnormalities.
The third and final checkpoint is the M checkpoint which occurs during metaphase. This checkpoint ensures that each kinetochore, a structure that connects the chromosome to the spindle fiber, is properly attached to a spindle fiber before the cell can proceed with mitosis.
