Learning Objectives:
- List the importance of mitotic division.
- Discuss major events in each phase of mitosis.
- Describe what goes wrong with a normal cell when it becomes cancerous.
- Introduction: The eukaryotic cell cycle allows the cell to grow and divide. In mitosis one parent cell produces two daughter cells with the same kind and amount of information (chromosomes) as the parent cells. The mitotic cell cycle is composed of the interphase and the M phase. A cell undertakes interphase prior to the M phase. The M phase is composed of the mitotic phases (prophase, metaphase, anaphase, and telophase), which divides the nucleus of the cell and cytokinesis, which divides the cytoplasm. As a result of one mitotic division, one parent cell produces two daughter cells genetically identical.
- To study and learn about mitosis do the following:
- To report on this lab for grade do the following: Mitosis Questions- Answer the following questions:
- Review chapter 9 of the Textbook and resources on the course website on Mitosis (Mitosis outlines, video clips, animation, and art quiz).
- Use your Textbook to characterize prophase, metaphase , anaphase, and telophase of mitosis.
- What are the purposes of mitotic division?
- What are the differences between plant cell and animal cell mitotic division?
- When do chromosomes first become visible in mitosis?
- Explain how do you distinguish between the terms chromosome, chromatin, and chromatid.
- During what stages of mitosis are chromosomes composed of two chromatids?
- During what stages of mitosis are chromosomes composed of one chromatid-single structure ?
- What goes wrong with a normal cell when it becomes cancerous?
- What are the causes of cancer? Explain.
