The cell cycle and cell division are fundamental processes in cell biology that ensure growth, repair, and reproduction in living organisms. The cell cycle consists of interphase (G1, S, and G2 phases) and mitotic (M) phase. During interphase, the cell grows, duplicates its DNA (S phase), and prepares for division. Mitotic phase includes mitosis (nuclear division) and cytokinesis (cytoplasmic division), resulting in two genetically identical daughter cells. Cell cycle regulation ensures accurate duplication and distribution of genetic material, critical for organismal development and maintenance. Dysregulation can lead to diseases like cancer.
