GENERAL HISTOLOGY

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

Detailed explanation-2: -Nucleus-The control center of the cell that directs all of the cell activities. Genetic material is contained inside. Usually found in center of cell. Nuclear Membrane-The outside boundary of the nucleus that controls what enters and exits the nucleus.

Detailed explanation-3: -The nuclear envelope allows control of the nuclear contents, and separates them from the rest of the cytoplasm where necessary.

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.

Detailed explanation-5: -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. Nucleoli are small bodies often seen within the nucleus.
