Cell cycle checkpoints are control mechanisms that hold the progression of the cell cycle to the next stage in the cell cycle until the conditions are favorable. They ensure proper cell division . The three most important cell cycle checkpoints are the G1 checkpoint, the G2 checkpoint, and the spindle assembly … Following DNA replication in S phase, the cell undergoes a growth phase known as G2. During this time, necessary mitotic proteins are produced and the cell is once more subjected to regulatory mechanisms to ensure proper status for entry into the proliferative Mitotic (M) phase. Multiple mechanistic checkpoints are involved in this transition from G2 to M, with a common uniting factor of cyclin … the internet connection was not stable
