What is Karyokinesis?
Karyokinesis is a process where the nucleus splits into two daughter nuclei during cell division. W. Schleicher coined the term “karyokinesis” in 1878. The term “karyokinesis” is derived from the Greek words “karyon,” meaning “nucleus” and “kinesis,” meaning “movement”. It is the first step of the cell cycle. Karyokinesis occurs only in cells that are in the G0 phase of interphase. During karyokinesis, DNA condenses and chromosomal material splits into two equal halves and line up in the middle of the cell.
The chromosome divide equally between the two new nuclei. The phases of karyokinesis include prophase, metaphase, anaphase, and telophase. Karyokinesis is followed by cytokinesis, which is the splitting of the cytoplasm and cell membrane. The purpose of mitosis is cell growth and to replace or regenerate damaged cells or tissues.
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.
