During which phase of mitosis do the chromosomes align in the center of the cell?
Correct answer
B
Rationale
The correct answer is Metaphase. During Metaphase, the chromosomes line up along the center of the cell's equator, forming the metaphase plate. This alignment ensures that during the subsequent phase, Anaphase, the sister chromatids can separate and move towards opposite poles. Prophase is the initial phase of mitosis where chromosomes condense and the nuclear envelope breaks down. Telophase is the final phase of mitosis where two new nuclei form.
