p53 gene is sort of a checkpoint in the cell cycle. if there is a error in the replicated DNA the p53 gene prevents the cell from entering into the mitotic phase. so now can u interpret the ans?

zpupster · Answer

The p53 gene is involved in cell cycle regulation and is thought to hold the cell in a particular phase until DNA defects are repaired. So, if p53 is defective, the cell continues the cell cycle and cell division without the benefit of a pause in the cell cycle that would allow the cell to repair damage, leading to a cell that accumulates DNA damage. A cell with a defective p53 wouldn't necessarily divide *regularly* but would continue dividing in an uncontrolled fashion.
