CELL CYCLE
Enduring Understandings
• Cells need to divide in a manner that creates new cells that are identical to
the original cell.
• Failure to cells to stop dividing appropriately is Cancer.
Essential Questions
• How do eukaryotic cells divide accurately?
• How do prokaryotic cells divide accurately?
• How is cell division controlled?
• How does this unit provide evidence for the theory of endosymbiosis?
• How does this unit provide evidence of the relatedness of living things in
the world?
• How do differences between and among cell division correlate to specific
functions and how is this evidence that living things are uniquely adapted
to their environment?
Targets
• Know the difference between the chromosome, chromatin, sister
chromatids.
• Diagram the cell cycle and describe the significant events occurring in
each phase.
• Provide a brief description of cancer. Be sure to relate it to mitosis.
• Describe what is meant by contact inhibition and how it acts to prevent the
uncontrolled division of cells. Explain how a change in a gene controlling
the cell cycle can result in cancer.
• Describe the three important checkpoints of the cell cycle and what can
happen if the checkpoints do not function properly.
