Karyokinesis:

Explanation

Karyokinesis, also known as nuclear division, is a crucial step in cell division, ensuring accurate distribution of genetic material to daughter cells. During this process, the replicated chromosomes condense and align along the metaphase plate in mitosis or homologous chromosomes pair up in meiosis. Next, the sister chromatids separate and move toward opposite poles of the cell during anaphase. Finally, in telophase, the separated chromosomes decondense, forming two distinct nuclei in mitosis, while in meiosis, two rounds of karyokinesis result in the formation of four haploid daughter cells. Karyokinesis is tightly regulated and ensures genetic stability and diversity in organisms' offspring. Any errors in this process can lead to genetic abnormalities and developmental disorders.
