A single cell is displayed. There are two purple centrioles and a red nucleus within the cell. The red nucleus contains two blue and two turquoise chromatin clouds. The four blue and turquoise chromatin clouds slowly condense to conform four, x-shaped chromosomes as the red of the nucleus fades away. The chromosomes move to form a single vertical line in the middle of the cell while the centrioles move to the far left and right sides of the cell. The purple centrioles send out spindle fibers that attach to the middle of each chromosome. The centromeres pull apart, dividing each X-shaped chromosome in half and pulling them to opposite sides of the cell, which begins to divide. As the cell splits in two, two new nucleus form to contain the chromosome halves as the spindle fibers dissolve. The chromosomes fade back out into chromatin clouds. The cells split completely into two daughter cells.
