Cell Cycle

Cell Cycle
2
Three Stages of the Cell Cycle

• Interphase
• G1
• S
• G2
• Mitosis
• Prophase
• Metaphase
• Anaphase
• Telophase
• Cytokinesis

• Use your text to identify what happens in each of
  the phases.
• You should be especially concerned with the
  nucleus, the cytoplasm, and the cell membrane
  (and the contents therein).

The Biology Project

• Look up the regulation of the cell cycle at
  http//www.biology.arizona.edu/Cell_bio/tutorials/
  cell_cycle/cells2.html
• Take notes
• In a journal explain how the cell cycle is
  regulated

4
Synthesis phase

• DNA replication takes place in Interphase during
  the S phase
• Complete pages 146-147
• Add marginalia in a color other than black as you
  read

5
The Biology Project

• Look up mitosis at http//www.biology.arizona.edu
  /Cell_bio/tutorials/cell_cycle/cells3.html
• Take notes
• In a journal explain what mitosis is and why its
  necessary

Mitosis! Everyone does it!

• Create an advertisement for Mitosis
• Convince the consumer that the process of mitosis
  allows for genetic continuity from generation to
  generation, but also provides diversity and
  therefore, is a must have!
• Make sure to inform them of the details of these
  facts
• the cell cycle assures genetic continuity
• mitosis allows for the even distribution of
  genetic information to new cells

Cytokinesis

• In a journal, compare and contrast the mechanisms
  of cytokinesis in animals and plants

Cancer

• Knowing how the cell cycle is regulated, in a
  journal, justify how aberrations in the cell
  cycle lead to tumor formation.
