Final answer:
Two processes that determine how quickly mutations accumulate within a cell are DNA Repair and alterations in cell-cycle control.
Step-by-step explanation:
Two processes that determine how quickly mutations accumulate within a cell are DNA Repair and alterations in cell-cycle control.
DNA Repair is a process that fixes mistakes that occur during DNA replication. If these mistakes are not corrected, they can lead to mutations. Therefore, cells with efficient DNA repair mechanisms accumulate mutations at a slower rate.
Alterations in cell-cycle control can also affect the rate of mutation accumulation. In cancer cells, mutations modify cell-cycle control, causing the cells to continuously divide without stopping. This uncontrolled division increases the chances of mutations occurring and accumulating within the cells.
