NEET BIOLOGY

Detailed explanation-1: -Nuclei contain the genetic material called DNA that is responsible for controlling and directing all cell activities.

Detailed explanation-2: -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.

Detailed explanation-3: -The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information.

Detailed explanation-4: -Nuclear Membrane The nuclear membrane serves to separate the chromosomes from the cell’s cytoplasm and other contents. An array of small holes or pores in the nuclear membrane permits the selective passage of certain materials, such as nucleic acids and proteins, between the nucleus and cytoplasm.
