Sometimes, these checkpoint genes are mutated or damaged and, thus, are unable to tell a damaged cell to stop dividing. When this occurs, the damaged cell gives rise to many damaged cells, which in turn create more damaged cells. These dividing cells form a Grade It Now Save & Continue Continue without saving W3 Quiz Back to Assignment Attempts: Average: 12 9.
