Nucleus, in biology, a specialized structure occurring in most cells and separated from the rest of the cell by a double layer, the nuclear membrane. This membrane seems to be continuous with the endoplasmic reticulum which is a membranous network of the cell and has pores, which probably permit the entrance of large molecules. The nucleus controls and regulates the activities of the cell e.g., growth and metabolis) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus. The gel-like matrix in which the nuclear components are suspended is the nucleoplasm.
