Which of the following describes a reason why the cell cycle is tightly regulated with checkpoints rather than proceeding continuously?
Show answer and explanation
Correct answer: To verify DNA is accurately replicated and errors repaired before division
Checkpoints monitor for DNA damage, proper replication, and accurate chromosome attachment to the spindle, thereby preventing propagation of genetic errors to daughter cells and maintaining genomic integrity.
