Document Summary

The appearance of the nucleus and its chromosomes tell us a lot about what stage of the cell cycle a given cell is in. Nuclear division is called mitosis and cytoplasmic division is called cytokinesis, and they usually happen together, but they are not necessarily linked. The cell cycle consists of an interphase stage (takes up most of the cycle) and a mitosis stage (just a little bit) The interphase stage has 3 parts: g1 phase o. You can"t see the chromosomes in the nucleus during interphase because they are in a diffuse state o. The granular chromatin (the stuff that eventually condenses to become chromosomes) is bounded by a distinct nuclear membrane, and sometimes you can see nucleoli within the chromatin. As for the nucleus, it looks the same through all 3 stages of interphase, so you can"t tell what part of interphase a cell is in by looking at the nucleus.
