    Which of the following is NOT a part of mitosis? - ProProfs

    Which of the following is NOT a part of mitosis?

    • Prophase

    • Interphase

    • Metaphase

    • Anaphase

    Correct Answer
    A. Interphase
  • 3. 
    The Cell Cycle begins, at which stage? - ProProfs

    The Cell Cycle begins, at which stage?

    • Mitosis

    • G1

    • G2

    • S

    Correct Answer
    A. G1
    Explanation
    The Cell Cycle begins at the G1 stage. This is the first stage of the cell cycle, where the cell grows and prepares for DNA replication. After the G1 stage, the cell enters the S phase, where DNA synthesis occurs, followed by the G2 phase, where the cell continues to grow and prepares for cell division. Finally, the cell enters the mitosis stage, where the nucleus divides into two identical daughter nuclei. Therefore, G1 is the correct answer as it is the initial stage of the cell cycle.

    Anaphase is where __________________________ - ProProfs

    Anaphase is where __________________________

    • The spindle fibers pull sister chromatids apart

    • DNA replicates

    • The nucleus dissolves

    • Chromosomes align at the center of the cell

    Correct Answer
    A. The spindle fibers pull sister chromatids apart
    Explanation
    During anaphase, the spindle fibers, which are formed by the centrosomes, contract and pull the sister chromatids apart. This separation occurs as the spindle fibers attach to the kinetochores of the chromosomes and exert a force that moves them towards opposite poles of the cell. This process ensures that each daughter cell receives an equal number of chromosomes during cell division.

    The G1 is the period of growth ________ the DNA is duplicated. - ProProfs

    The G1 is the period of growth ________ the DNA is duplicated.

    • Before

    • After

    • During the time when

    Correct Answer
    A. Before
    Explanation
    The G1 phase is the period of growth in the cell cycle that occurs before the DNA is duplicated. During this phase, the cell prepares for DNA replication by increasing its size and synthesizing proteins necessary for cell division. Once the DNA is duplicated, the cell enters the S phase to proceed with DNA replication. Therefore, the correct answer is "before."

    S is when __________________ - ProProfs

    S is when __________________

    • The cytoplasm has finished dividing

    • The cell grows

    • Cell division begins

    • The DNA is replicated

    Correct Answer
    A. The DNA is replicated
    Explanation
    When the DNA is replicated, it indicates that the cell is in the S phase of the cell cycle. During this phase, the cell prepares for division by duplicating its DNA. This is a crucial step in cell division as it ensures that each daughter cell receives a complete set of genetic information. Once the DNA is replicated, the cell can proceed to the next phase, which is cell division. Therefore, the correct answer is when the DNA is replicated.

    The last step of the cell cycle is ____________. - ProProfs

    The last step of the cell cycle is ____________.

    • Metaphase

    • G2

    • Cytokinesis

    • Anaphase

    Correct Answer
    A. Cytokinesis
    Explanation
    Cytokinesis is the final step of the cell cycle. It is the process by which the cytoplasm of a cell is divided into two daughter cells after the nuclear division (mitosis or meiosis) has occurred. During cytokinesis, the cell membrane pinches inwards, creating a cleavage furrow in animal cells or a cell plate in plant cells, ultimately leading to the separation of the two daughter cells. This ensures that each daughter cell receives a complete set of genetic material and necessary organelles to function independently.

    Rate this question:

  • 8. 
    Cell division starts to take place at _________ - ProProfs

    Cell division starts to take place at _________

    • Telophase

    • Prophase

    • Interphase

    • Anaphase

    Correct Answer
    A. Telophase
    Explanation
    Cell division starts to take place at telophase. Telophase is the final stage of mitosis, the process of cell division. During telophase, the nuclear envelope reforms around the separated chromosomes, and the chromosomes begin to decondense. This marks the completion of cell division and the formation of two daughter cells. Therefore, telophase is the stage where cell division begins.
