What are the 4 phases of a typical cell cycle and the events occurring during each phase?
You can leave an optional "tip" with Mahalo's virtual currency, Mahalo Dollars. If you are asking a difficult question that might require some research, or if you'd like a wide variety of feedback, a higher tip often leads to more answers to your question.

Super short version:
(*Gap 0- the cell is not active in the cycle, normal activity)
*Gap 1- the cell grows larger, allowing room for materials in preparation for synthesis of DNA
*Synthesis- DNA replication
*Gap 2- cell gos back to growing in preparation for the next stage
*Mitosis:
Prophase- chromosomes fold or visually shorten and thicken and pair up with their matching chromosomes, connecting at the centromere
Metaphase-chromosomal pairs 'line up' in the center of the cell
Ananphase-chromosomes spilt the paired sister chromatids and pull them apart, with one of each set heading towards opposite ends of the cell
Telophase-nuclear envelope grows between the two populations of chromosomes, chromosomes unfold back into their normal state
*Cytokineseis- cell membrane starts pinching in, ultimately dividing the two sides into separate sister cells.
Oh, and http://www.cellsalive.com/cells/3dcell.htm has a few really short nice learning/memory aids.
