Give the detailed information about the Nucleus.
Answers
Answer:
The nucleus is the information centre of the cell and is surrounded by a nuclear membrane in all eukaryotic... A cell normally contains only one nucleus. Under some conditions, however, the nucleus divides but the cytoplasm does not.
Nucleus, in biology, a specialized structure occurring in most cells (except bacteria and blue-green algae) 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 (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 metabolism) 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.
