____ In the process of cell division, the division of the cell nucleus is called
A
mitosis
B
Mitochondria
C
membranes
D
mesothelioma
Explanation: 

Detailed explanation-1: -Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.

Detailed explanation-2: -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-3: -Mitosis is the process of cell division wherein the chromosomes replicate and get equally distributed into two daughter cells. The chromosome number in each daughter cell is equal to that in the parent cell, i.e., diploid. Hence, mitosis is known as equational division.

Detailed explanation-4: -There are two kinds of nuclear division-mitosis and meiosis. Mitosis divides the nucleus so that both daughter cells are genetically identical. In contrast, meiosis is a reduction division, producing daughter cells that contain half the genetic information of the parent cell.
