G2 checkpoint

Patent Pending Following the decision to enter the cell cycle and undergo division, the cell goes through S phase, in which it replicates its DNA, and, in most species, G2, in which it undergoes rapid growth and protein synthesis in preparation for mitosis, the process of cell division. The G2/M checkpoint, also known as the DNA damage checkpoint, ensures that the cell underwent all of the necessary changes during the S and G2 phases and is ready to divide.
