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.

Mitotic cyclins will be broken down, and the cell will go from G2 to M phase.

Explanation:

The cell cycle represents the series of events that occurs in a cell from its preparation for cell division till the end. The cell cycle consists of two main stages viz: the interphase stage and the mitotic stage. The interphase stage is further divided into the G1, S and G2 phases.

A set of internally controlled mechanisms called CHECKPOINTS ensure that each phase occurs smoothly without errors. If not, the cell won't advance to the next stage. The cell prepares for mitotic process in the Interphase state where it specifically replicates its DNA in the S-PHASE and enlarges in the G2 phase.

Upon succesful completion of these interphase stages, the cell is then cleared to proceed to the mitotic stage to undergo division.

Hence, mitotic cyclins, which are a group of proteins that regulate the progression of the cell cycle, will be broken down, and the cell will go from G2 to M phase once the DNA of a cell has been replicated, and the cell is fully grown and developed.
