Question: The division of the nucleus is known as: (NSCL 2019)
Options:
Cytokinesis
Karyokinesis
Anaphase
Metaphase
📌 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.
–Â 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.
