A. Chromosomes start to coil up and become visible
B. Chromosome line up on the equator of the cell
C. Chromatids reach the poles of the spindle
D. Chromatids separate and move to opposite poles
Explanation
In metaphase, the chromosomes (now consisting of two sister chromatids each) align themselves at the center of the cell, attached to the microtubules of the mitotic spindle.
This forms the metaphase plate, where each chromosome is positioned at the equator of the cell, ready for separation.
