Chromosomes and nuclear membrane. each chromosome is shaped like a "x" and makes two sisters chromatid. each chromotid is is identical to he one right attached to it. they are attached by a structure called centomere.
The sister chromotiads get pulled by the parts of the spindle apparatus to the middle of the line, where they form a vertical line.
In this stage the chromotads separate and migrate to other ends of the spindle.
During it each set of chromosomes move to to the edge of the cell membrane. Then a nuclear membrane forms making an new nuclei.
