Which process is the main cell division that includes metaphase and anaphase, occurring after the G2 phase and ending with cytokinesis?

• A. Meiosis
• B. Cytokinesis
• C. Mitosis
• D. Interphase

Answer: (C)

Mitosis is the division of the nucleus that organizes and separates the cell’s replicated chromosomes. It includes stages like metaphase, where chromosomes align at the cell’s center with spindle fibers attached, and anaphase, where sister chromatids are pulled apart to opposite poles. After mitosis, cytokinesis splits the cytoplasm to form two distinct daughter cells. This sequence occurs after the G2 phase, the final stage of interphase when DNA has been replicated. Meiosis involves two rounds of division and is for producing gametes, not the typical somatic cell division described here, and interphase is the growth and DNA-replication period, not a division stage.
