उत्तर
Chromosomes get aligned at the center of the cell during metaphase.
Explanation:
During metaphase, spindle fibres attach to the centromeres of the condensed chromosomes and exert a coordinated pull. This mechanical tug-of-war moves all the chromosomes to the spindle equator, perfectly lining them up end-to-end along the centre of the cell (known as the metaphase plate). This critical alignment ensures that when the chromosomes split in the next stage, each new daughter cell will receive an exact, identical set of DNA.
