Mitosis
THE PROCESS WHERE A SINGLE CELL DIVIDES RESULTING IN GENERALLY TWO IDENTICAL CELLS, EACH CONTAINING THE SAME NUMBER OF CHROMOSOMES AND GENETIC CONTENT AS THAT OF THE ORIGINAL CELL.
Interphase
Divided into G1, S and G2 phases.
During these phases the cell spends greater part of its time and performs the majority of its purpose such as cell division.

Prophase
Preparation for cell division occurs.
The nucleus disappears, the chromatin gets denser and forms chromatids. The two pairs of centrioles move to opposite poles. In the cytoplasm, the mitotic spindle forms from the MTOC or centrioles.

Metaphase
The final preparation before the chromatids separate.
The sister chromatids replicated chromosomes are aligned in the middle of the cell at the metaphase plate.

Anaphase
The centromere of each chromosome divides.
Each newly formed chromosome move apart to separate the sister chromatids into two single-stranded chromosomes.
Each newly formed chromosome move apart to separate the sister chromatids into two single-stranded chromosomes.
Telophase
Two nuclei form to separate sister chromosomes.
Polar fibers elongate by adding more microtubules using ATP to expand the cell. Two new nuclei form to envelope the two new groups of daughter chromosomes. Nucleoli reappear inside each nucleus. The chromosome loosen to become chromatin again.

Cytokinesis
Cell splits into two.
The cytoplasm furrows inward in the case of animal cells makings a cleavage furrow. In the case of plant cell, a cell plate forms to divide the two daughter cells, each with its nucleus, chromosomes, organelles etc. The resulting cells are identical in DNA content and number of chromosomes.
