Cell Cycle
 * 1) Draw an animal cell (irregular shape, eukaryote). Label the cell membrane, cytoplasm, centrioles, nucleus, nuclear membrane, chromatin (DNA) and nucleolus (dense spot in the nucleus).
 * 2) Draw a comic strip with three stages. Show an animal cell (irregular shape) before, during and after cell division.
 * 3) Draw a circle and divide it into four equal sections. Draw an arrow indicating movement clockwise. Label the regions in sequence G1, S, G2, M. Put a star next to all of the phases that would be part of Interphase. Define interphase on your whiteboard.
 * 4) List the four stages of the cell cycle: G1, S, G2, M. Briefly describe what is occurring during each stage.

Growth Rates (Human cells)
 * 1) Draw an outline of the human body. Label the following cells: Skin cells, Muscle Cells, Brain Cells (Neurons). Rank them 1, 2, 3 for fastest to divide (1), medium (2), and slowest (3).
 * 2) List the following types of cells in order of division (fastest first). Provide an explanation for why they would be ranked how you ranked them: Intestinal lining, Bacteria, Cardiac muscle (Heart) cells.

Additional practice
 * 1) Draw a DNA molecule. Label the Deoxyriboses (Sugars), Phosphates, Adenine, Guanine, Cytosine, Thymine and Hydrogen bonds.
 * 2) Critique your model to make sure your deoxyriboses connect with your nitrogen bases (AT and GC) not in between them. Make it include double-ringed purine nitrogen bases (A and G) and single-ringed pyrimidine nitrogen bases (C and T). Also, add two hydrogen bonds (=) between A and T and three hydrogen bonds between G and C. Check to see if your Deoxyriboses are larger than your phosphates (smaller).
