Questions and Answers
  • 1. 

    Are cells active during Interphase?

    • A.

      Yes

    • B.

      No

    Correct Answer
    A. Yes
    Explanation
    During interphase, cells are indeed active. Interphase is a phase in the cell cycle where cells grow, replicate their DNA, and prepare for cell division. It is a crucial stage for cellular activities such as protein synthesis, metabolism, and organelle replication. Although cells are not actively dividing during interphase, they are still carrying out essential functions necessary for their growth and maintenance. Therefore, the correct answer is "Yes."

    What is the first phase of Mitosis?

    • A.

      Metaphase

    • B.

      Anaphase

    • C.

      Prophase

    • D.

      Telophase

    Correct Answer
    C. Prophase
    Explanation
    Prophase is the correct answer because it is the first phase of mitosis. During prophase, the chromatin condenses into chromosomes, the nuclear membrane breaks down, and the spindle fibers begin to form. This phase prepares the cell for cell division by organizing the genetic material and setting the stage for the subsequent phases of mitosis.

    During ________ the spindle fibers shorten.

    • A.

      Telophase

    • B.

      Metaphase

    • C.

      Prophase

    • D.

      Anaphase

    Correct Answer
    D. Anaphase
    Explanation
    During anaphase, the spindle fibers shorten. This is an important step in cell division where the sister chromatids are pulled apart towards opposite poles of the cell. The shortening of the spindle fibers is responsible for the movement of the chromatids and their separation. In telophase, the spindle fibers elongate, in metaphase, the spindle fibers attach the chromatids to the spindle apparatus, and in prophase, the spindle fibers start to form and lengthen.

    When dose the nuclear envelope break down making the nucleus no longer recognizable?

    • A.

      Prometaphase

    • B.

      Anaphase

    • C.

      Metaphase

    • D.

      Telophase

    Correct Answer
    A. Prometaphase
    Explanation
    During prometaphase, the nuclear envelope breaks down, allowing the chromosomes to be fully exposed and interact with the spindle fibers. This breakdown of the nuclear envelope makes the nucleus no longer recognizable as a distinct structure. In prometaphase, the chromosomes also start to move towards the center of the cell, preparing for their eventual separation in anaphase. Therefore, prometaphase is the correct answer as it is the stage where the nuclear envelope breaks down and the nucleus becomes unrecognizable.

  • 5. 

    When do the daughter chromosomes arrive at the poles and the spindle fibers that pulled them apart disappear?

    • A.

      Anaphase

    • B.

      Telophase:

    • C.

      Metaphase

    • D.

      Prometaphase

    Correct Answer
    B. Telophase:
    Explanation
    In telophase, the daughter chromosomes arrive at the poles and the spindle fibers that pulled them apart disappear. This is the final stage of mitosis, where the nuclear envelope reforms around each set of chromosomes at opposite poles of the cell. The spindle fibers disassemble and the cell prepares for cytokinesis, the division of the cytoplasm.
