Karyokinesis vs. Cytokinesis: Know the Difference
By Shumaila Saeed || Published on December 28, 2023
Karyokinesis is the division of a cell's nucleus during mitosis or meiosis, while cytokinesis is the process where the cell's cytoplasm divides, forming two daughter cells.
Key Differences
Karyokinesis involves the division of the cell's nucleus, where chromosomes are duplicated and separated into two nuclei. Cytokinesis, on the other hand, is the division of the cell's cytoplasm, resulting in the physical separation into two daughter cells.

Karyokinesis occurs before cytokinesis during cell division. Once karyokinesis is completed, ensuring that each new nucleus has the correct number of chromosomes, cytokinesis begins to divide the cell into two.

In karyokinesis, structures like spindle fibers play a crucial role in chromosome separation. Cytokinesis involves the formation of a cleavage furrow in animal cells or a cell plate in plant cells to divide the cytoplasm.

Karyokinesis ensures genetic material is accurately distributed to each daughter nucleus, a key aspect of genetic stability. Cytokinesis is crucial for physically separating the divided nuclei and ensuring each new cell has the necessary cellular components.

Karyokinesis is a universal process in eukaryotic cell division, whether in animals, plants, or fungi. Cytokinesis, while also universal, varies in its mechanism between plant and animal cells.

Karyokinesis
The indirect division of cells in which, prior to division of the cell protoplasm, complicated changes take place in the nucleus, attended with movement of the nuclear fibrils; - opposed to karyostenosis. The nucleus becomes enlarged and convoluted, and finally the threads are separated into two groups which ultimately become disconnected and constitute the daughter nuclei. Called also mitosis.
