Question

during which phase of mitosis do chromosomes align at the center (equator) of the cell? anaphase metaphase prophase telophase

Explanation:

Mitosis has four main phases: Prophase (chromosomes condense, spindle forms), Metaphase (chromosomes align at the cell's equator), Anaphase (sister chromatids separate), and Telophase (nuclear envelopes reform). The question asks when chromosomes align at the center, which is the key event of Metaphase.

Answer:

B. Metaphase (Note: Assuming the options are labeled as A. Anaphase, B. Metaphase, C. Prophase, D. Telophase for clarity, the correct one is B. Metaphase)
