Durning which stage of the cell cycle does cell division occur
Cell division occurs during the mitotic stage of the cell cycle.
Cell division occurs during the M phase (Mitosis phase) of the cell cycle.
Cell division, or mitosis, occurs during the third stage of the cell cycle, known as the "M phase." The cell cycle consists of four main stages:
1. G1 (Gap 1) phase: This is the first growth phase where the cell grows in size, prepares to replicate DNA, and carries out its normal functions.
2. S (Synthesis) phase: In this phase, DNA replication takes place, resulting in the formation of identical copies of the cell's genetic material.
3. G2 (Gap 2) phase: The second growth phase occurs after DNA replication. During this phase, the cell continues to grow and prepares for cell division by synthesizing various proteins and organelles.
4. M (Mitosis) phase: This is the final stage of the cell cycle where cell division occurs. It is divided into four distinct steps: prophase, metaphase, anaphase, and telophase.
During prophase, the DNA condenses and becomes visible as chromosomes, and the nuclear membrane breaks down. In metaphase, the chromosomes line up at the center of the cell. Anaphase is characterized by the separation of sister chromatids, which are pulled apart by the spindle fibers towards opposite poles of the cell. Finally, in telophase, new nuclear membranes form around the separated chromosomes, and the cell undergoes cytokinesis.
So, cell division occurs during the M phase of the cell cycle, specifically during the stages of mitosis.
