Question
In which stage of mitosis the chromosomes align in an equatorial plate? How?
Solution
The chromosomes align in an equatorial plate during metaphase stage of mitosis. Each chromosome gets attached to a spindle fibre by its centromere which is known as the chromosomal fibre. During metaphase the sister chromatids are pulled back and forth until they align along the equator of the cell called equatorial plane.
