Cells pass through a G2 checkpoint before entering mitosis. Ideally, if DNA damage is detected, the cells do not enter mitosis until the damage is repaired. Why is DNA damage repaired before cells enter mitosis.

• To ensure that the cell has enough energy for mitosis
• To prevent the transmission of damaged DNA to daughter cells
• Because DNA damage prevents the formation of the mitotic spindle
• Because DNA repair mechanisms are only active during mitosis
