Answer:
Interphase:
The DNA is present as uncondensed chromatin, which is not visible under a microscope. The DNA is contained within a clearly defined nucleus . Centrosomes and other organelles have been duplicated , and the cell is enlarged in preparation for division .
Prophase:
The DNA supercoils and chromosomes condense, becoming visible under a microscope). The chromosomes are comprised of genetically identical sister chromatids, which are joined at a centromere). Paired centrosomes then move to the opposite poles of the cell and form microtubule spindle fibers , the nuclear membrane breaks down, and the nucleus dissolves .
Metaphase:
The microtubule spindle fibers from both centrosomes connect to the centromere of each chromosome , microtubule depolymerisation causes spindle fibers to shorten in length and contract , causing chromosomes to align along the center of the cell.
Anaphase:
The continued contraction of the spindle fibers cause genetically identical sister chromatids to separate . Once the chromatids separate, they are individual chromosomes. The genetically identical chromosomes move to the opposite poles of the cell .
Telophase:
Once the two chromosome sets arrive at the poles, spindle fibers dissolve and chromosomes decondense, becoming invisible under light microscopes. Nuclear membranes reform around each chromosome set , and cytokinesis occurs concurrently, splitting the cell into two separate cells.
