 Life Cycle
Cells divide as time passes, as this occurs they pass through 3 checkpoints G1, G2 and Metaphase.
This is illustrated
here
through an animation click on check point for succint descriptions of each checkpoint.
Cells divide a certain number of times, then they die. On average this occurs 30 time per lifespan,
then father time takes its toll and ageing then occurs.
