Difference Between Karyokinesis and Cytokinesis
The difference between Karyokinesis and Cytokinesis are as follows:
| Feature | Karyokinesis | Cytokinesis |
|---|---|---|
| Definition | Division of the cell nucleus, involving chromosomes. | Division of the entire cell, including the cytoplasm. |
| Occurs in | Both eukaryotic mitosis and meiosis. | Follows karyokinesis in mitosis and meiosis. |
| Nature | Nuclear division. | Cytoplasmic division. |
| Process | Involves the separation of chromosomes into daughter cells. | Involves the division of the cytoplasm and organelles. |
| Timing | Precedes cytokinesis. | Follows karyokinesis. |
| Purpose (Mitosis) | Formation of two identical daughter nuclei. | Formation of two identical daughter cells. |
| Purpose (Meiosis) | Formation of four non-identical haploid daughter cells. | Meiosis involves two rounds of karyokinesis. |
| Result | Two daughter nuclei with the same genetic material. | Two daughter cells with the same genetic material. |
| Components Affected | Nucleus and chromosomes. | Cytoplasm, organelles, and cell membrane. |
| Location in the Cell Cycle | Occurs during the M phase (mitosis and meiosis). | Typically occurs immediately after karyokinesis. |
| Cellular Outcome | Determines the genetic makeup of daughter cells. | Establishes two separate, fully functional cells |
What is Karyokinesis?
Karyokinesis is the process of nuclear division that occurs during cell division mitosis or meiosis, specifically in eukaryotic cells. It is the first step in the M phase of the cell cycle. It is followed by cytokinesis, which is the splitting of the cytoplasm and cell membrane. Karyokinesis is divided into five phases Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis.
The process of karyokinesis allows the growth and expansion of multicellular organisms. It also enables the regeneration of damaged tissues. In this article, we will study Karyokinesis, the stages of karyokinesis, its significance, and the difference between karyokinesis and cytokinesis.
