04: Cell Cycle

  • Define interphase.

    Define interphase.

    Interphase is the phase in the cell cycle when the cell is not dividing, and it undergoes growth, DNA replication, and preparation for cell division.

  • What is mitosis?

    What is mitosis?

    Mitosis is the process of cell division that results in two genetically identical daughter cells.

  • Name the stages of mitosis.

    Name the stages of mitosis.

    The stages of mitosis are: 1. Prophase 2. Metaphase 3. Anaphase 4. Telophase

  • Define meiosis.

    Define meiosis.

    Meiosis is a type of cell division that reduces the chromosome number by half, producing four non-identical daughter cells, which are essential for sexual reproduction.

  • Differentiate between mitosis and meiosis.

    Differentiate between mitosis and meiosis.

    Mitosis results in two genetically identical diploid cells, while meiosis results in four genetically different haploid cells. Mitosis occurs in somatic cells, whereas meiosis occurs in germ cells.

  • What is the significance of the cell cycle?

    What is the significance of the cell cycle?

    The cell cycle is essential for growth, repair, and reproduction of cells, allowing organisms to grow and maintain tissue function.

  • Define cytokinesis.

    Define cytokinesis.

    Cytokinesis is the final step in the cell cycle where the cytoplasm divides, forming two distinct daughter cells.

  • What is the role of checkpoints in the cell cycle?

    What is the role of checkpoints in the cell cycle?

    Checkpoints regulate the cell cycle by ensuring that the cell only progresses to the next phase if conditions are favorable and errors are corrected.

  • What is the end product of meiosis?

    What is the end product of meiosis?

    The end product of meiosis is four non-identical haploid cells, each containing half the number of chromosomes as the original cell.

  • Explain the stages of the cell cycle.

    Explain the stages of the cell cycle.

    The cell cycle consists of two main stages: Interphase and Cell Division. Interphase includes three sub-stages: G1 Phase (cell grows and performs normal functions), S Phase (DNA replication), and G2 Phase (preparation for mitosis). Cell Division includes mitosis (nuclear division) and cytokinesis (cytoplasmic division).
