Karyokinesis (Gr. Karion - Core, Kinesis - Movement)

Karyokinesis is the processes occurring in the cell nucleus during mitosis.

During karyokinesis, genetic material is distributed between daughter cells. Karyokinesis includes the following stages:

  1. Prophase - chromosomes condense and become visible under a microscope. The nuclear membrane disintegrates.

  2. Metaphase - chromosomes line up in the equatorial plane of the cell. A metaphase plate is formed.

  3. Anaphase - homologous chromosomes move to opposite poles of the cell.

  4. Telophase - chromosomes reach the poles and begin decondensation. The nuclear membrane and nucleolus are restored.

Thus, during the process of karyokinesis, the genetic material is evenly distributed between the two daughter cells, which ensures their genetic identity to the mother cell. Karyokinesis is an essential part of mitosis.
