Presentation Transcript


Sample question
Sample Question

  • If the S phase were eliminated from the cell cycle, the daughter cells would

    • Have half the genetic material found in the parent cell

    • Be genetically identical to each other

    • Be genetically identical to the parent

    • Synthesize the missing genetic material on their own


Sample question1
Sample Question

  • Select from one of the choices that best fits the description

    • Telophase

    • Interphase

    • Cytokinesis

    • Prophase

    • Anaphase

Descriptions

  • Cytokinesis during this final stage of mitosis

  • Division of cytoplasm

  • Sister chromatids separate

  • Genetic material replicates



Sample questions
Sample Questions

  • After which of the following checkpoints in the cell cycle is the cell first committed to divide?

    • G2 checkpoint

    • M checkpoint

    • Interphase checkpoint

    • G1 checkpoint

    • MPF checkpoint


Maturation promoting factor mpf
Maturation Promoting Factor (MPF)

  • Composed of cyclin bound to a cyclin dependent protein kinase

    • CDK

      • constant concentration

      • Active only when bound to cyclin

    • Cyclin

      • Concentration varies during the cell cycle


Changes in cyclin concentration
Changes in CyclinConcentration


Practice problem
Practice Problem

  • Look at Figure 7.9 in your handout and read through the investigation

    • What was the purpose of radioactive labeling

    • Why would you expect more radioactive labeling of DNA during S phase

    • What were the percentages of cells in S phase in each of three experiments provided?

    • What does that suggest in terms of control of cell cycle?
