Document Summary

Here is the eucaryotic cell cycle illustrated in a basic way. Here we start off with a single cell and then that cell divides. A key aspect of this is that the material in the cell has to duplicate itself. If the cell is going to divide, a lot of material has to be produced so the cell cycle is important to have cell growth which is illustrated in this simple cartoon. You can see the increased size of this cell, so that"s the increased growth of membranes, increased growth of the cytoskeleton, for example, mitochondria, er membranes, Golgi membranes so there"s enough material to divide into 2 for the next round. If during mitosis, certain chromosomes were lost, then of course that"s going to cause problems as well. Here is the cell cycle in more detail, broken into specific phases.
