__________________ __________________ __________________ Mitosis Flip Book Your Task? Your task is to create an “index card” flip movie that illustrates and mimics the movement in the ‘basic’ steps of Cell Cycle: 1. The first card is the cover. Write the underlined title: The Phases of Mitosis, along with your name, date and period on the cover. Also, include a colored picture of an animal cell. 2. Make four flip cards for each of the following stages of the Cell Cycle: Interphase Prophase Metaphase Anaphase Telophase Cytokinesis 3. You will draw the cell, organelles, and chromosomes as they change for the Cell Cycle, splitting it into four parts so the motions appear very smooth. Hand draw and color each cell picture neatly and accurately. Make each cell the ‘same’ size and color. 4. At the back of the flip book, devote one card to each of the above stages to explain that part. Write the name of the stage at the top, underline the name of the stage and copy the descriptions exactly as they are below. Interphase: The time before mitosis, The cells may appear inactive during this stage, but they are quite the opposite. This is the longest peiod of the complete cell cycle. The cells enlarge, preparing for mitosis. The DNA replicates, or copies itself. The cell grows and makes structures to use during the rest of the cell cycle. Prophase: During this first mitotic stage: The chromatin in the nucleus condenses and becomes visible chromosomes. Each replicated (copied) chromosome is made of two chromosomes, both with the same genetic information. Spindle fibers begin to form around the centrioles. The nucleur membrane breaks down. The centrioles are moving to opposite ends of the cell. Then, the chromosomes double and are moving towards the middle Metaphase: The “middle” phase. The centromere attaches the chromatids to the spindle fibers. Tension applied by the spindle fibers aligns all chromosomes at the center of the cell. Anaphase: The chromatids (daughter chromosomes) separate, the spindle fibers shorten, and the chromatids are pulled apart and begin moving to the cell poles. The spindle fibers get shorter. The chromatids arrive at the poles (opposite ends of the cell) Telophase: The nuclear membrane forms around the chromosomes. The spindle fibers that have pulled them apart disappear. The cell membrane is beginning to pinch the cytoplasm. Cytokinesis: The middle of the ‘cell’ cleaves into two cells. The chromosomes thicken and become longer The result is two identical daughter cells that are also identical to the original parent cell. The book should be held together by something stable. Either tape, use staples, use binder clips, or find some other substitute. Please alert the teacher if any supplies are difficult to obtain. See pictures and the text book for assistance. Illustrations need to be drawn freehand. Take your time. Grades will be based on following the directions as written above and oral quizzes about the stages of the Cell Cycle. Due October 4th
