The cell is engaged in metabolic activity and performing its prepare for mitosis.


Chromatin in the nucleus begins to condense and becomes visible in the light microscope as chromosomes.

Spindle fibers align the chromosomes along the middle of the cell nucleus.

The paired chromosomes separate at the kinetochores and move to opposite sides of the cell.

Chromatids arrive at opposite poles of the cell, and new membranes form around the daughter nuclei.

In animal cells, cytokineses results when a fiber ring composed of a protein called actin around the center of the cell contracts pinching the cell into two daughter cells, each with one nucleus.
