H.W. To really understand how a disease happens, we must understand how the processes are supposed to be when they run normally. So do the following starting with the lecture first:
1. Bozeman Biology Lecture on Mitosis, Meiosis and the Cell Cycle (mostly mitosis)
2. Construct a working model of mitosis using the pipe cleaners that you were given in class. You should have a total of 4 pipe cleaner (2 pipe cleaners should be one color and 2 pipe cleaners should be another color)
Cut these pipe cleaner in half. Now you should have 4 pipe cleaners of 1 color and 4 pipe cleaners of one color. This will help you construct your model of mitosis of an organism with the chromosome number 2n=4. Your model must show what the pipe cleaner chromosomes do during each phase of the cell cycle: Interphase (G1, S, G2), and Mitosis (Prophase, Metaphse, Anaphase, Telophase and Cytokinesis)
Follow Mr. Anderson's model for help.
