Questions and Answers
  • 1. 

    During which stage of the cell cycle does DNA replicate?

    • A.

      G1

    • B.

      S

    • C.

      G2

    • D.

      M

    Correct Answer
    B. S
    Explanation
    During the S phase of the cell cycle, DNA replication occurs. This is the stage where the cell prepares to divide by duplicating its genetic material. DNA replication is a crucial step in cell division as it ensures that each daughter cell receives an identical copy of the genetic information. The S phase is followed by the G2 phase, where the cell continues to prepare for division by synthesizing proteins and organelles. Therefore, the correct answer is S.

    What does cytokinesis produce?

    • A.

      Two daughter cells

    • B.

      Two DNA copies

    • C.

      A much larger cell

    • D.

      A dead cell

    Correct Answer
    A. Two daughter cells
    Explanation
    Cytokinesis is the final stage of cell division, where the cytoplasm divides to form two separate daughter cells. During cytokinesis, the cell membrane pinches inwards, creating a cleavage furrow or cell plate, which eventually separates the two daughter cells. Therefore, the correct answer is two daughter cells.

    What are the three stages of interphase?

    Correct Answer
    G1 S G2, g1 s g2
    Explanation
    The three stages of interphase are G1, S, and G2. During G1, the cell grows and carries out its normal functions. S phase is the synthesis phase, where DNA replication occurs. In G2, the cell continues to grow and prepares for cell division. These stages are important for the cell to ensure proper growth and replication before entering the mitotic phase.

  • 4. 

    When does the cell cycle begin?

    • A.

      After cell growth

    • B.

      After DNA replication

    • C.

      Before mitosis

    • D.

      After cytokinesis

    Correct Answer
    D. After cytokinesis
    Explanation
    The cell cycle is a series of events that occur in a cell leading to its division and duplication. After cytokinesis, which is the final stage of the cell cycle where the cytoplasm divides and two daughter cells are formed, the cell cycle begins again. This is because the daughter cells need to grow, replicate their DNA, and undergo mitosis in order to divide further. Therefore, the cell cycle begins after cytokinesis.

    The cell cycle is another name for the __________ cycle of the cell

    • A.

      Life

    • B.

      Death

    • C.

      Division

    • D.

      Reproduction

    Correct Answer
    A. Life
    Explanation
    The cell cycle refers to the series of events that a cell goes through as it grows and divides. It includes phases such as cell growth, DNA replication, and cell division. Therefore, the cell cycle is synonymous with the life cycle of a cell, as it encompasses all the stages from the birth of a cell to its division into two new cells.

    Rate this question:

  • 6. 

    During which phase of the cell cycle does the cell grow larger?

    • A.

      G1

    • B.

      S

    • C.

      G2

    • D.

      M

    Correct Answer
    A. G1
    Explanation
    During the G1 phase of the cell cycle, the cell grows larger. This phase is also known as the gap phase 1, where the cell prepares for DNA replication. It is during this phase that the cell accumulates the necessary resources and energy to support the upcoming S phase, where DNA synthesis occurs. The G1 phase is a critical checkpoint where the cell assesses its environment and internal conditions before committing to DNA replication and cell division.

    Rate this question:

  • 7. 

    Which stage of the cell cycle cause the daughter cells to have the same amount of DNA?

    • A.

      Cytokinesis

    • B.

      Mitosis

    • C.

      Interphase

    • D.

      G0

    Correct Answer
    B. Mitosis
    Explanation
    During mitosis, the cell undergoes several stages, including prophase, metaphase, anaphase, and telophase. One of the key events that occurs during mitosis is the separation of duplicated chromosomes into two daughter cells. This ensures that each daughter cell receives an equal amount of DNA, resulting in both cells having the same amount of genetic material. Therefore, mitosis is the stage of the cell cycle that causes the daughter cells to have the same amount of DNA.

    Rate this question:

  • 8. 

    During which stage of the cell cycle does the cell divide into two daughter cells?

    • A.

      G1

    • B.

      S

    • C.

      G2

    • D.

      M

    Correct Answer
    D. M
    Explanation
    During the M phase of the cell cycle, the cell divides into two daughter cells through a process called mitosis. This phase is characterized by the separation of duplicated chromosomes into two sets and the division of the cytoplasm to form two distinct cells. It is the final stage of the cell cycle and ensures the accurate distribution of genetic material to the daughter cells.

    How does the cell cycle help our bodies heal?

    • A.

      The cell cycle produces new healthy cells to replace dead ones with growth happening in mitosis and cell division happening during interphase.

    • B.

      The cell cycle produces new healthy cells to replace dead ones with growth happening in interphase and cell division happening during mitosis.

    • C.

      The cell cycle creates new DNA to fix the damaged cells.

    • D.

      New cells move from healthy parts of your body to replace the damaged parts.

    Correct Answer
    B. The cell cycle produces new healthy cells to replace dead ones with growth happening in interphase and cell division happening during mitosis.
    Explanation
    The cell cycle is a process that allows our bodies to heal by producing new healthy cells to replace dead or damaged ones. During interphase, the cell grows and prepares for division, while during mitosis, the cell divides into two identical daughter cells. This ensures that the damaged or dead cells are replaced with new, functioning cells, promoting healing and maintaining the overall health of our bodies.
