During which phase of mitosis do chromosomes line up along the middle of the cell (the metaphase plate)?

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

Answer: (D)

Verified step by step guidance

1. Recall the main phases of mitosis: prophase, metaphase, anaphase, and telophase.
2. Understand that during prophase, chromosomes condense and the mitotic spindle begins to form.
3. Recognize that metaphase is characterized by chromosomes aligning at the cell's equatorial plane, known as the metaphase plate.
4. Know that during anaphase, sister chromatids are pulled apart toward opposite poles of the cell.
5. Remember that telophase involves the reformation of the nuclear envelope around the separated chromatids and the beginning of cytokinesis.
