In normal cell division, cells follow a tightly regulated cycle known as the cell cycle. This cycle includes phases such as Interphase (G1, S, and G2 phases) and M phase (mitosis and cytokinesis). Regulatory proteins like cyclins and cyclin-dependent kinases (CDKs) ensure that each phase progresses correctly. If errors are detected, mechanisms like apoptosis (programmed cell death) eliminate the faulty cells to maintain tissue health.
