    Question: The division of the nucleus is known as: (NSCL 2019)

    Options:

    Cytokinesis
    Karyokinesis
    Anaphase
    Metaphase

    ✅ Explanation: Karyokinesis is the process of nuclear division, where the nucleus divides into two daughter nuclei

    📌 Other Options Explanations:
    -Cytokinesis is the division of the cytoplasm, which usually follows karyokinesis
    -Anaphase and metaphase are stages of mitosis (a type of karyokinesis).

    🔑Key Points:
    -Cytokinesis is the process by which the cytoplasm of a eukaryotic cell divides into two daughter cells after mitosis or meiosis.
    – During cytokinesis, a contractile ring made of actin and myosin filaments forms around the cell, which then contracts and divides the cytoplasm into two parts.
    – In animal cells, cytokinesis results in the formation of a cleavage furrow, while in plant cells, a cell plate forms in the middle of the cell and grows outward until it reaches the cell wall.
    -Cytokinesis is a crucial step in cell division, as it ensures that each daughter cell receives a complete set of chromosomes and other cellular components necessary for survival.

    •  🛑Additional Information:
    -Sepsis is a potentially life-threatening condition caused by the body's response to an infection. It has no relation to cytokinesis.
    -Karyokinesis is the division of the nucleus of a eukaryotic cell into two daughter nuclei during cell division. It is different from cytokinesis, which involves the division of the cytoplasm.
    -Genesis refers to the beginning or origin of something and has no relation to cell division or cytokinesis.
