Science is a multidisciplinary field of knowledge comprising three key subjects, namely Physics, Biology, and Chemistry. The three are divided in their relative fields . For example, Physics deals with gravity, inertia, kinetics, force, etc., while Chemistry deals with chemical compounds, reactions, formulas, periodic tables, etc. Biology is also very different because it talks about plants, animals, and humans.
Humans and their related systems, animals, food chain, plants, chlorophyll, photosynthesis, etc., fall under Biology. Biology is a major theme of biodiversity. Now, two words in Biology have great significance, namely, Cytokinesis and Karyokinesis. Both of these terms are related to cell formation and division. You must be wondering what these words mean. Therefore, let us first understand the meaning of Cytokinesis and Karyokinesis, following the differences between the two.
What is Karyokinesis?
This is the first stage of mitosis. Karyokinesis is part of the nucleus of a cell that leads to two female nuclei. The whole process takes place in 5 stages: Prophase, Prometaphase, Metaphase, Anaphase and Telophase.
Prophase – This is the first stage of Karyokinesis that separates repetitive genes that carry the parent nucleus and form two female cells.
Prometaphase – This is the second stage of Karyokinesis. Here the membrane around the nucleus breaks.
Metaphase -The third stage of Karyokinesis where the chromosomes found in the parent nucleus are formed in a straight line between cells is Metaphase.
Anaphase – This is the fourth stage of Karyokinesis in which repetitive chromosomes are separated and new chromosomes are formed at both ends of the cell.
Telophase – This is the fifth and final stage of Karyokinesis. This initiates the formation of two female nuclei shortly after the new chromosomes and duplicated chromosomes are drawn to the opposite sides of the cell.
What is Cytokinesis?
This is the second process that starts after Karyokinesis and you need to know that this is another process from Karyokinesis. Sometimes Cytokinesis is not part of the mitosis process and makes the process itself completely different which leads to the formation of a single cell but has many nuclei in it. For example, mold, slime fungus and coenocytic algae. Unlike Karyokinesis, Cytokinesis is a simple procedure with no stages involved.

1 |
The technique of division of the nucleus is referred to as Karyokinesis |
Cytokinesis is referred to as the system of division of cytoplasm. |
|
2 |
Two daughter nuclei are divided from a nucleus. |
The daughter cells equally acquire the divided nuclei, cellular organelles, and cytoplasm. |
|
3 |
Do not rely on Cytokinesis. |
cannot take the region without Karyokinesis getting involved |
|
4 |
For the technique to initiate, the M segment is step one. |
M phase is the second step for the Cytokinesis to begin the technique. |
|
5 |
Karyokinesis takes location earlier than Cytokinesis and the nucleus gets divided earlier than the cytoplasm. |
Cytokinesis takes the area after Karyokinesis and the nucleus gets divided after the cytoplasm. |
Symptoms of Cytokinesis
-
Cytokinesis occurs at the end of the process of meiosis and mitosis. This process helps to differentiate the daughter cells.
-
The formation of a contractile ring is an important step in Cytokinesis. This is how the process begins.
-
The contract ring contains cytoskeleton proteins.
-
The plasma membrane binds together and separates after reaching the ring.
-
The daughter’s heads are facing. The cell is in the middle.
-
The cell is divided equally so that there is a nucleus in each girl’s cells.
-
Cell plate formation occurs in plants, and embryonic separation occurs in animals.
Symptoms of Karyokinesis
-
The process of cell division during mitosis is called Karyokinesis.
-
Karyokinesis is the first step that occurs during cell division.
-
Cell regeneration occurs in Karyokinesis.
-
Tissues, organelles, and cells function well under Karyokinesis.
-
The genes are distributed evenly so that each female cell has a nucleus in it.
Therefore, these are some of the features of Cytokinesis and Karyokinesis. Both of these processes are important for all living things as cell division is essential for their occurrence. In addition, both Cytokinesis and Karyokinesis occur in plants, animals and humans. Thus, both processes are essential for supporting life on earth.
