During which phase of mitosis do the chromosomes line up along the middle of the dividing cell?
Correct answer: B. Metaphase
- A. Prophase
- B. Metaphase
- C. Telophase
- D. Anaphase
Explanation
During metaphase of mitosis, the chromosomes align along the metaphase plate, an imaginary plane equidistant between the two poles of the cell. Each chromosome's centromere is attached to spindle fibers originating from opposite poles of the cell. This alignment ensures that each daughter cell will receive an identical set of chromosomes during cell division. Metaphase is a critical checkpoint in mitosis, ensuring the proper alignment of chromosomes before they are separated and distributed to the daughter cells during anaphase.
