Role of mitosis in cell cycle
Storyboard Text
- ouch my knee!!
- Ow, mikkey!!
- I have check your knee miss, you are going to be okay now. Are you familiar of mitosis?? By of it, your scratch will heal fast.
- *cries*I dont clearly understand what is the role of mitosis sir.
- The phase your cells are in now is Interphase.
- Interphase is when the cell duplicates to prepare for mitosis. Technically, it is not part of mitosis but rather encompasses G1, S, and G2 in cell cycle.
- Huh?? can you explain further sir?
- It was All Souls day when Mikkey and her family went to visit their loved ones in the cemetery. She and her cousins were playing when suddenly she stumbled and fell on the ground. Her mother hurriedly bring her to the hospital.
- By the way, Spindle Fibers are the cytoskeleton structure that forms during cell division, AKA Mitosis.
- Oh, I see. Amazing!!
- The nurse came in and looked at her knee. He explained to Mikkey how mitosis helps with cell growth and heals broken bones and wounds faster along with its 6 stages; Interphase, Prophase, Metaphase, Anaphase, Telophase, and lastly, Cytokinesis.
- in Annaphase the cells move from the opposite poles from each other.
- I feel almost completely healed already!
- The nurse explains what happened during Interphase, which is before mitosis begins, then the cells grow and the chromatin start replicating. He also explains to Mikkey that the Interphase has three main parts; G1, S, and G2.
- about several weeks later....
- Since you now know all about the Cell Cycle and Mitosis, you're all set! You've been fully healed!!
- The first step in MITOSIS is the Prophase, which is when the chromosomes become visible as paired chromatids and the nuclear envelope disappears. He explained that the second step is called the Metaphase, in this stage the cells move towards the middle and attatch to the spindle.
- During the Prophase, this is where the nucleus disappears and chromosomes separate. Along with Metaphase, spindle fibers pull sister chromatids and line them up in the middle of the celll, which is called the "equator".
- The nurse explained to MIickkey how the Anaphase helps her heal by creating more cells. This is helpful to her because the cells are in the process of producing more cells. Furthermore, The nuclear membrane & nucleus begin to reform around chromosomes. The Nucleolus becomes visible again. Finally, spindle fibers break down.
- In Telophase the cell divides in two and continues this process over and over.
- Right after Telophase, Cytokinesis begins. During Cytokinesis, the Cytoplasm is completely divided. A Cleavage Furrow forms and the cytoplasm divides, therefore creating 2 new daughter cells. After this stage, the cycle of cells is complete, and it cycles back through continuously to continue forming new cells.
- YAY!!!
