Which mitotic phase is characterized by the chromosomes arriving at the poles and the nuclear envelope reformation?

• A. Prophase
• B. Metaphase
• C. Anaphase
• D. Telophase

Answer: (D)

In telophase, the final stage of mitosis, the chromosomes arrive at opposite poles and begin to de-condense back into thread-like chromatin. The nuclear envelope reforms around each set of chromosomes, creating two distinct nuclei within the cell. The nucleolus reappears inside these new nuclei, and the spindle apparatus dismantles as the cell prepares for cytokinesis to finish dividing the cytoplasm. This phase is distinct from prophase (chromosomes condense and the nuclear envelope breaks down), metaphase (chromosomes align at the center), and anaphase (sister chromatids separate and move to the poles).
