2.2.1 Mitosis

Cards (24)

  • Mitosis involves the replication and equal division of DNA
  • In which phase of mitosis do chromosomes align at the center of the cell?
    Metaphase
  • What is the primary role of mitosis in multicellular organisms?
    Growth and development
  • What happens to cells during tissue repair after an injury?
    Mitosis creates new cells
  • During the G1 phase, Cyclin D activates CDK4 and CDK6
  • Mitosis produces two genetically identical daughter cells.
  • What type of cell division is mitosis?
    Cell division
  • During interphase, the cell replicates its DNA
  • Nuclear envelopes reform during telophase.
    True
  • Mitosis enables the differentiation of cells into tissues and organs during embryonic development.

    True
  • Cell cycle checkpoints monitor the completion of key events before the cell progresses to the next phase.

    True
  • Why is the regulated system of mitosis important?
    Prevents uncontrolled cell division
  • Mitosis results in two genetically identical daughter cells.
    True
  • During prophase, the nuclear envelope breaks down.

    True
  • Match the significance of mitosis with its description:
    Growth ↔️ Increases organism size
    Development ↔️ Differentiation of cells into tissues
    Tissue Repair ↔️ Replaces damaged cells
    Asexual Reproduction ↔️ Generates new individuals from a single parent cell
  • Match the function of mitosis with its description:
    Tissue Repair ↔️ Replaces damaged cells
    Asexual Reproduction ↔️ Creates new individuals from a single parent cell
  • Which molecules control the progression through the cell cycle?
    Cyclins and CDKs
  • Mitosis and meiosis both result in the same number of daughter cells.
    False
  • What are three purposes of mitosis in multicellular organisms?
    Growth, repair, reproduction
  • During anaphase, sister chromatids move to opposite poles
  • Mitosis allows organisms to increase in size
  • The regulation of mitosis ensures proper cell division and prevents uncontrolled cell growth
  • Match the cell cycle phase with its key cyclins and CDKs:
    S phase ↔️ Cyclin E and CDK2
    G2 phase ↔️ Cyclin A and CDK1
    M phase ↔️ Cyclin B and CDK1
  • What is the primary purpose of meiosis?
    Sexual reproduction
