In a normal cell cycle, the DNA of a cell has been replicated, and the cell is fully grown and developed. What will most likely happen next? Cyclin degradation will cause the cell to go from M phase to G1. Cell inhibitors will inactivate the CdKs, preventing cell mitosis. The G1 cyclins will increase, and the cell will go from G1 to S phase. Mitotic cyclins will be broken down, and the cell will go from G2 to M phase.
