The Problem: How do
cells faithfully distribute genetic material to daughter cells?
The Issue: Each time a cell divides the daughter
cells must get the right chromosomes. For example, cells with missing
or extra chromosomes will corrupt DNA and can become
cancerous.
Basics of
chromosome movement
Mitosis is the mechanism that allows the nuclei of cells to split and
provide each daughter cell with a complete set of chromosomes during cellular
division. This, coupled with cytokinesis (division of the cytoplasm), occurs
in all multicellular plants and animals to permit growth in living organisms.
Steps of
mitosis "Cell Division"

Cytokinesis: The cytoplasm divides,
creating two separate cells. Cytokinesis starts during anaphase and is
completed after telophase. In animals, a contractile ring of actin and myosin,
pinches the cell in two.
The above steps of cellular mitosis is only one
important phase
of the life of a cell--the phase during which genetic information is
separated into two new nuclei and the cell divides.
