Quizplus · Accepted Answer

The p53 protein plays multiple roles in the regulation of the cell cycle. It can halt cell division when necessary to allow for DNA repair, and it can induce the death of cells with heavily damaged DNA that cannot be repaired, a process known as apoptosis. Additionally, p53 can prevent the cell from dividing at inappropriate times, such as when DNA replication is incomplete or during the G1 checkpoint of the cell cycle. Therefore, all of the above statements are true, making option D the best choice.
