What is the main function of control mechanisms in the cell cycle?

To prevent DNA mutation

To regulate cell division

The main function of control mechanisms in the cell cycle is to regulate cell division. These mechanisms ensure that the cell progresses through the different phases of the cycle—such as G1, S, G2, and M—at the appropriate times and under the right conditions. Cell cycle regulators, including cyclins and cyclin-dependent kinases, play a crucial role by activating or inhibiting certain processes that dictate when a cell should divide, repair itself, or enter a state of dormancy. This regulation is vital for maintaining cellular integrity, preventing uncontrolled proliferation, and ensuring successful DNA replication and mitosis. By controlling these processes, the cell cycle mechanisms help maintain the balance of growth and division in tissues, thus playing a key role in development, tissue repair, and overall homeostasis.
