Detailed explanation-1: -Diagrams in biology textbooks usually depict the nucleus as a spheroid in the center of the cell. However, the position of nuclei varies dramatically from this simple view. Nuclei are frequently positioned asymmetrically depending on cell type, stage of the cell cycle, migratory state and differentiation status.

Detailed explanation-2: -A nucleus is a double-membrane bounded cell organelle present in eukaryotic cells. It controls the functioning of the cell. It contains chromosomes, through which heredity characters are passed from one generation to the other.

Detailed explanation-3: -Most eukaryotic cell types usually have a single nucleus, but some have no nuclei, while others have several. This can result from normal development, as in the maturation of mammalian red blood cells, or from faulty cell division.

Detailed explanation-4: -It’s in the middle of the cell, and the nucleus contains all of the cell’s chromosomes, which encode the genetic material.
