Which process is division of the nucleus?

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

Answer: (D)

Division of the nucleus happens during mitosis. After the DNA is replicated in interphase, mitosis organizes and separates the chromosomes so two new nuclei form, each with a complete chromosome set. The process ensures genetic material is evenly distributed into the daughter cells, and it is typically followed by cytokinesis, which splits the cytoplasm to complete cell division. In contrast, interphase is the period of growth and DNA replication before any nuclear division; cytokinesis is the final split of the cytoplasm, not the nucleus; and meiosis is another type of nuclear division that occurs in reproductive cells and involves two rounds of division to produce gametes with half the chromosome number.
