Dividing a eukaryotic cell in two is not trivial. This page gives information beyond what is normally discussed and is meant to be a supplement to a normal course of instruction. The centrosome is a neglected cell organelle, yet is absolutely essential for eukaryotic cell division and cell structural organization.
Calcium plays a crucial factor on cell signaling.
Certain proteins react to the presence of calcium to turn on and off other proteins in the cell. Calcium concentrations are critical to the entire mitotic cycle. Calcium is released into the cytoplasm at the correct time from internal stores in vesicles associated with the mitotic apparatus. Centrosome - provides the organizing matrix for keeping all the players in formation. Chromosomes - condensed DNA, carrying the genetic information of the cell.
