NEET BIOLOGY

Detailed explanation-1: -The nucleus contains genetic information (DNA) on special strands called chromosomes. Function-The nucleus is the “control center” of the cell, for cell metabolism and reproduction.

Detailed explanation-2: -The nucleus, formed by a nuclear membrane around a fluid nucleoplasm, is the control center of the cell. Threads of chromatin in the nucleus contain deoxyribonucleic acid (DNA), the genetic material of the cell.

Detailed explanation-3: -Nucleus is known as the control center of the cell as it performs the following functions: The nucleus contains the hereditary material of the cell, the DNA. It sends signals to the cells to grow, mature, divide and die. The nucleus is surrounded by the nuclear envelope that separates the DNA from the rest of the cell.

Detailed explanation-4: -The cell’s entire activity is monitored by the nucleus. It serves as the control room for cell functions as well as the repository for the cell’s DNA.

Detailed explanation-5: -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.
