Class Summary - We started out class today with a quiz on protein synthesis. Today we used a mimio presentation as we discussed the mitotic phase of the cell cycle. The mitotic phase includes both mitosis and cytokinesis. We discussed what happened looked at a real life picture of a cell in that phase and used a color diagram handout to look at each phase. We used the acronym PMAT to help us remember the phases; prophase, metaphase, anaphase and telophase. During prophase spindle fibers connect to the centromere and chromosomes shorten and thicken. During metaphase, chromosomes line up in the 'middle' of the spindle. This will appear as chromosomes are two sister chromatids aligned at the equator of the cell. Anaphase is when the chromatids actually pull 'apart' and are separated. The chromosomes move to opposite sides of the cell. During telophase chromosomes begin to unravel and become chromatin again, nuclear envelope reassembles and there are two distinct nuceli as the cell begins to 'tear' apart. After mitosis, cytokinesis happens where we actually have created two complete cells.
Homework - Study for Wedneday's Test
Objectives - Students will identify, from pictures, each phase of mitosis. Students will explain what happens during each phase of mitosis.
