Today, we finished our powerpoint presentation on the steps of mitosis for a fruit fly cell. Mitosis is the process in which a parent cell divides, or reproduces asexually to create two daughter cells or create a new cell. Some of the information that should be on your powerpoint is:
Phase 1 (Interphase): The chromatins in the nucleous replicate. The cell condenses. This one of the longest stages. Proteins are being produced.
Phase 2 (Prophase): The cell condenses. The chromatins turn into chromosomes. The nucleous begins to disappear. Centrosomes turn into centreols.
Phase 3 (Metaphase): The centreols make spindle fibers which attach to centromeres. The chromosomes line up. The nucleous is completely gone.
Phase 4 (Anaphase): The spindle fibers split the chromosomes. They pull to different ends of the cell.
Phase 5 (Telophase): The two nuclei form and the chromosomes unwind and turn back into chromatins.
Phase 6 ( Cytokinesis): When the cell splits into two daughter cells, there are now two nuclei. One in each cell. There is no more membrane binding the two cells together. They stay near eachother, but they are still two seperate cells.
