Cell Cycle Introduction
The cell cycle involves both the growth and division of a cell. The life and length of a cell varies by the particular type, yet Eukaryotic cells undergo a process of cell growth and carrying metabolic functions (interphase) and division (mitosis & cytokinesis)
- Mitosis is division of the nucleus into two genetically identical daughter nuclei
- Chromosomes condense by supercoiling during mitosis
- Cytokinesis occurs after mitosis and is different in plant and animal cells
- Interphase is a very active phase of the cell cycle with many processes occurring in the nucleus and cytoplasm
- Partner with one other student (table group of 4) or two students (table group of three).
- Watch the Mitosis & Cytokinesis animation from McGraw Hill
- On your notes packet, describe the events of interphase and mitosis (the specifics of interphase will be discussed in the homework video).
- Pretend we have a mythical creature that has three chromosomes pairs (humans have 46) arranged in three pairs (chromosome 1, 2, & 3). This organism has chromosomes from dad (blue) and a chromosome from mom (red).
- Using the following vocabulary, chromosome cutouts, nucleus cut outs, and cell diagram for our mythical creature, create a model to represent each of the following stages (including interphase and specifically S Phase). After completing each stage outlined below, take a picture using a phone; be ready to show and explain your pictures to Rott.
- Stages of Cell Cycle:
- Partner A: Start of Interphase
- Partner A: End of Interphase
- Partner B: Prophase
- Partner A: Metaphase
- Partner B: Anaphase
- Partner A: Telophase
- Partner B: Explain how mitosis produces two genetically identical nuclei
- Sister Chromatid
- Nuclear Envelope
- Each stage of Mitosis
