Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The process by which a cell nucleus divides is called:
A
interphase
B
mitosis
C
cytokinesis
D
cell cycle
Explanation: 

Detailed explanation-1: -Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. The word “mitosis” means “threads, ” and it refers to the threadlike appearance of chromosomes as the cell prepares to divide.

Detailed explanation-2: -Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells.

Detailed explanation-3: -A membrane forms around each set of chromosomes to create two new nuclei. The single cell then pinches in the middle to form two separate daughter cells each containing a full set of chromosomes within a nucleus. This process is known as cytokinesis.

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.

Detailed explanation-5: -Another name for cell division is “mitosis.” If you study biology, you’ll learn about cell division, when a cell divides into two smaller “daughter cells.” During cell division, all the tiny elements of the cell also divide-including the cell’s chromosomes, nucleus, and mitochondria.
