Question

these are important points in the cell cycle that look for errors and stop the process if errors are detected to prevent changed cells

Explanation:

Cell cycle checkpoints monitor for errors in DNA replication, chromosome attachment, etc. If errors are found, they halt the cell cycle to prevent the production of abnormal cells. Cell cycle is the overall process of cell growth and division. Interphase is the phase where cell grows and replicates DNA. Apoptosis is programmed cell death. But the description in the question matches checkpoints as they specifically look for errors and stop the process.

Answer:

Checkpoints
