The Cell Cycle

Let's review a little about the cell cycle and its components to understand colectoral cancer.


Questions and Answers
  • 1. 
    How many phases to the cell cycle are there?
    • A. 

      1

    • B. 

      3

    • C. 

      4

    • D. 

      5

  • 2. 
    What phases make up the cell cycle?
    • A. 

      Gap 1, Synthesis, Meiosis, Calvin Phase

    • B. 

      Gap 1, Synthesis, Gap 2, Mitotic Phase

    • C. 

      Gap 1, Gap 2, Mitotic Phase, Cell Signaling Pathway

    • D. 

      Mitotic Phase, Synthesis, Growth 1, Growth 2

  • 3. 
    What occurs during the Mitotic phase of the cell cycle?
    • A. 

      Replication of DNA

    • B. 

      Cell growth of organelles and proteins

    • C. 

      Division of cells into haploid gametes

    • D. 

      Mitosis and Cytokinesis

  • 4. 
    What is the role of cyclins and CDKs in the cell cycle?
    • A. 

      Cyclins activate cyclin-dependent kinases that form the protein kinase during G2

    • B. 

      Cyclins are a regulatory protein while CDKs are protein kinases that are active only when attached to particular cyclin that regulate transition out of fap phases

    • C. 

      Cyclins are named for the "roundness" of the cell cycle and CDKs are the proteins that prmote this "roundness"

    • D. 

      Cyclins and CDKs do not have a role in the cell cycle

  • 5. 
    MPFs stand for what and do what?
    • A. 

      Mitotic Proten Function that aids in development and functioning of proteins

    • B. 

      Maturation Promoting Factor that promotes DNA maturation

    • C. 

      Maturation Promoting Factor that includes cyclins and CDks and triggers progression through the cell cycle

    • D. 

      Maturation Promoting Factor that does not serves to speed up cancer

  • 6. 
    Check all that apply to Growth Factors
    • A. 

      Protein

    • B. 

      Must be present in extracellular environment

    • C. 

      Aid in growth and development of cells

    • D. 

      Can be local regulators that act on cells

    • E. 

      Stimulate cell proliferation

    • F. 

      Stimulate cell differentiation
