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

Answer: (A)

Verified step by step guidance

1. Understand the question: The problem is asking which phase of mitosis involves the movement of chromosomes to opposite poles of the cell. Mitosis is the process of cell division that ensures equal distribution of chromosomes to daughter cells.
2. Review the phases of mitosis: Mitosis consists of four main phases: Prophase, Metaphase, Anaphase, and Telophase. Each phase has distinct characteristics.
3. Recall the key events of each phase: In Prophase, chromosomes condense and the nuclear envelope breaks down. In Metaphase, chromosomes align at the cell's equatorial plane. In Anaphase, sister chromatids are pulled apart to opposite poles. In Telophase, the nuclear envelope reforms around the separated chromosomes.
4. Focus on the phase where chromosomes move to opposite poles: This movement is facilitated by the spindle fibers pulling the sister chromatids apart during Anaphase.
5. Conclude that the correct phase is Anaphase, as it is specifically characterized by the separation and movement of chromosomes to opposite poles of the cell.
