Detailed explanation-1: -Division of the nucleus during cell division is called karyokinesis and is followed by Cytokinesis, the division of the cell cytoplasm. Metakinesis is the separation of sister chromatids and their movement to opposite poles during anaphase stage of mitosis.

Detailed explanation-2: -Division of the nucleus during cell division is called karyokinesis and is followed by cytokinesis which is the division of the cell cytoplasm. Both karyokinesis and cytokinesis are parts of the cell cycle. Karyokinesis occurs in all four stages-prophase, metaphase, anaphase and telophase.

Detailed explanation-3: -Mitosis and meiosis, which are both forms of division of the nucleus in eukaryotic cells, share some similarities, but also exhibit distinct differences that lead to their very different outcomes. Mitosis is a single nuclear division that results in two nuclei, usually partitioned into two new cells.

Detailed explanation-4: -Karyokinesis, also known as mitosis, is divided into a series of phases-prophase, prometaphase, metaphase, anaphase, and telophase-that result in the division of the cell nucleus (Figure 10.2. 2). Karyokinesis is also called mitosis.

Detailed explanation-5: -meiosis, also called reduction division, division of a germ cell involving two fissions of the nucleus and giving rise to four gametes, or sex cells, each possessing half the number of chromosomes of the original cell.
