Cell division, or mitosis (normal cell division;
meiosis results in sex cells), occurs in four phases:
The chromosomes pair up. By this time, the chromosomes
have replicated so that the parent cell has two
complete sets. The cell forms two poles and the
The chromosomes align at the equator between both
The chromosomes divide, one of each copy heading
toward each pole. The cell membrane begins to divide.
Nuclei appear at either pole and the membrane divides.
Two cells exist, each with identical chromosomes.
