Cell Division Worksheet #2 Mitosis and Meiosis Demonstration (You will use this worksheet to track your attempts to model the cell cycle. Submit this worksheet through the assignment tab in iCollege. You may also fill in the sheet by hand and scan or take pictures and submit them.) Student Name: Phases of Interphase Take a picture of each phase of interphase as you work through the demonstration and paste it in the appropriate place. Also state the key event happening at each phase. G1 – (Cell Growth) S – (DNA Replication) G2 – (Confirmation that all chromosomes are copied) Phases of Mitosis Take a picture of each phase of mitosis as you work through the demonstration and paste it in the appropriate place. Also state the key event happening at each phase. Prophase – (Chromosomes Condense) Prometaphase – (Nuclear Envelope Breaks Down) Metaphase – (Sister Chromatids Line Up Along The Center Of The Cell) Anaphase – (Sister Chromatids Seperate) Telophase – (Nuclei Reform) Phases of Meiosis Take a picture of each phase of meiosis as you work through the demonstration and paste it in the appropriate place. Also state the key event happening at each phase. Prophase I – (Chromosomes condense and start crossing over) Prometaphase I – (Nuclear Envelope breaks down) Metaphase I – (Homologous chromosomes line up in the center of the cell) Anaphase I – (Homologues seperate) Telophase I – (Nuclei Reform) Prophase II – (Nuclear envelops breaks down in each daughter cell) Prometaphase II – (begin to align in the center of the cell) Metaphase II – (Spindle apparatus is complete in each daughter cell) Anaphase II – (chromosome move to opposite poles in the spindle) Telophase II – (nuclear envelope form around each set of chromosomes)
