    Study Notes

    The Cell Cycle

    • The two main stages of the cell cycle in eukaryotic cells are Interphase and M phase.
    • Cell division, where the cell divides into two daughter cells, is called Mitosis.

    Interphase

    • During Interphase, the cell grows, replicates its DNA, and prepares for cell division.
    • The main event that takes place during Interphase is DNA replication, which occurs during the S phase.
    • The cell prepares for cell division by replicating its organelles and cytoplasm.

    M Phase

    • The M phase involves the separation of replicated chromosomes, organelles, and cytoplasm into two daughter cells.
    • During the M phase, the cell undergoes Mitosis, where the replicated chromosomes are separated, followed by Cytokinesis, where the cytoplasm divides.
    • Cytokinesis occurs during the M phase, where the cytoplasm divides, and the cell splits into two daughter cells.

    Cell Cycle Checkpoints

    • Cell cycle checkpoints are control mechanisms that ensure the proper replication of cellular components and division.
    • The purpose of cell cycle checkpoints is to monitor and regulate the cell cycle, preventing errors during DNA replication and cell division.

    Eukaryotic Cells

    • Eukaryotic cells have a cell nucleus and undergo the cell cycle.
    • The main characteristic of eukaryotic cells that distinguishes them from prokaryotic cells is the presence of a cell nucleus.
    • Eukaryotic cells, such as plants and animals, undergo a more complex cell cycle than prokaryotic cells, like bacteria.
