DNA (Deoxyribonucleic Acid) contains all the information for cells to live, perform their functions and reproduce. Inside the nucleus is another organelle called the nucleolus.

Detailed explanation-2: -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-3: -The nucleus, formed by a nuclear membrane around a fluid nucleoplasm, is the control center of the cell.

Detailed explanation-4: -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.
