Answer:
Instable behavior.
Explanation:
The checkpoints currently behaving instable in sally cancer cells because mutants show genetic instability so this instability is the cause of cancer disease. Two checkpoints are sensitive to DNA damage, one occur before mitosis cell division and the other occur before replication of DNA. So damage occur in these two check points leads to instable behavior of cancer cells.
