regulation of cell division

Cell division is carefully controlled by a system of signals and checkpoints to ensure cells grow, duplicate their DNA, and divide correctly. Proteins called regulators send messages to start or halt division based on the cell’s condition, such as DNA damage or proper replication. If these controls fail, cells may divide too much or incorrectly, leading to problems like cancer. Precise regulation maintains healthy tissue growth, replaces worn-out cells, and prevents abnormal growth, ensuring the body functions properly. This intricate system balances the need for cell renewal with the prevention of uncontrolled growth.
