The part of the cell cycle that controls the repair of damaged DNA is the G2 phase. During G2, the cell checks for DNA damage and ensures that all DNA has been replicated correctly before proceeding to mitosis (M phase). If there is damage that cannot be repaired, mechanisms such as cell cycle checkpoints can prevent the cell from dividing, helping to avoid the types of abnormal cell division that can lead to cancer.
Which part of the cell cycle controls the repair of damaged DNA which, if unsuccessful, could eventually result in the abnormal cell division that typifies some types of cancer?

G1
G2
