During which cell division do two genetically identical daughter cells form for growth and tissue repair?

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

Answer: (B)

Two genetically identical daughter cells form during mitosis, the process that preserves the genetic material while the cell divides. In mitosis the nucleus splits so the two daughter nuclei have identical chromosome sets, and then cytokinesis divides the cytoplasm to produce two separate, genetically identical cells. This is essential for growth and tissue repair because it replaces damaged or lost cells with exact genetic copies. Meiosis, by contrast, creates gametes with half the chromosome number and introduces variation; cytokinesis alone doesn’t guarantee genetic identity since it’s just the cytoplasmic split, and karyokinesis refers to nuclear division itself without completing the formation of two separate cells. So mitosis is the right process.
