The cell cycle is the series of events through which a eukaryotic cell passes as it undergoes growth, DNA replication, and division.
Consisting of interphase (G1, S, and G2 phases) and the mitotic phase (mitosis and cytokinesis), the cell cycle ensures the accurate transmission of genetic material to daughter cells.
During interphase, cells prepare for division by growing and replicating DNA. Mitosis divides the nucleus, and cytokinesis separates the cytoplasm, completing the cycle. Regulation of the cell cycle is critical for normal cellular function and plays a role in development, growth, and tissue repair.
