Detailed explanation-1: -By housing the cell’s genome, the nucleus serves both as the repository of genetic information and as the cell’s control center.
Detailed explanation-2: -The nucleus (plural, nuclei) houses the cell’s genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins. Inside the nucleus, chromatin (DNA wrapped around proteins, described further below) is stored in a gel-like substance called nucleoplasm.
Detailed explanation-3: -Because nucleus contains a material called gene which controls all activities of cell and its characteristics. Cell nuclei contain most of the cell’s genetic material, organized as multiple long linear DNA molecules in complex with histones, to form chromosomes.
