The function of the nucleus is to store a cell's hereditary material, or DNA, which helps with and controls a cell's growth, function, and reproduction. The nucleus is an organelle found in eukaryotic cells and functions as the holder of a cell's blueprint The key function of the nucleus is to control cell growth and multiplication. This involves regulating gene expression, initiating cellular reproduction, and storing genetic material necessary for all of these tasks. In order for a nucleus to carry out important reproductive roles and other cell activities, it needs proteins and ribosomes Very briefly, the function of a nucleus is to preserve the integrity of these genes and to preside over the activities in the cell by regulating gene processing and other functionalities. There's no fixed shape to the nucleus. Though in most cases they're round or elliptical, oval shaped or disc-shaped nuclei have also been observed 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 Holding and protecting the cell's genetic material is the most important function of the nucleus, as this chromosomal DNA controls which genes are expressed, and which proteins are synthesized, essentially directing all activities that go on in the cell
One of the main functions of the nucleus is to carry DNA in the form of chromatin. It also duplicates DNA. While eukaryotes have a nucleus packed with DNA, prokaryotes and archaea do not.
