  1. Question 1

    What is the cell cycle?

    • AThe series of events that takes place in a eukaryotic cell from its formation to its division
    • BThe process of protein synthesis only
    • CThe process of respiration only
    • DThe process of producing gametes only
    Show answer

    Answer: A

    The cell cycle is the series of events from cell formation to division into two daughter cells.

  2. Question 2

    Into which two main phases is the cell cycle divided?

    • AInterphase and mitosis phase
    • BG1 and S phase
    • CG2 and M phase
    • DProphase and metaphase
    Show answer

    Answer: A

    The cell cycle consists mainly of interphase and the mitosis phase.

  3. Question 3

    Approximately what percentage of the total cell-cycle time is spent in interphase?

    • A90%
    • B10%
    • C25%
    • D50%
    Show answer

    Answer: A

    Interphase lasts for about 90% of the total time of the cell cycle.

  4. Question 4

    What does a cell mainly do during interphase?

    • APerforms its life functions and prepares for division
    • BDivides its cytoplasm only
    • CSeparates sister chromatids
    • DForms four daughter cells
    Show answer

    Answer: A

    During interphase the cell performs its functions and prepares for the next division.

  5. Question 5

    What is another name for the G1 phase?

    • AFirst Gap Phase
    • BFirst Growth Division
    • CFirst Synthesis Phase
    • DFirst Mitosis Phase
    Show answer

    Answer: A

    G1 stands for the First Gap Phase and is also called the growth phase.
