It is the command center of a eukaryotic cell and is commonly the most prominent organelle in a cell accounting for about 10 percent of the cell's volume. Information in DNA is transcribed, or copied, into a range of messenger ribonucleic acid (mRNA) molecules, each of which encodes the information for one protein (in some instances more than one protein, such as in bacteria). When a cell is "resting", or not dividing, its chromosomes are organized into long entangled structures called chromatin. The cell nucleus contains a nuclear membrane, which is referred to as the nuclear envelope, nucleolus, nucleoplasm, and chromosomes. Such nuclear pores are the sites for exchange of large molecules (proteins and RNA) between the nucleus and cytoplasm. Please refer to the appropriate style manual or other sources if you have any questions. The cell membrane gives the cell its shape and helps keep bad material out while also ferrying good material in. lysosomes. Learn how your comment data is processed. To understand more about the role of the nucleus, read about the structure and function of each of its parts. The nucleolus contains nucleolar organizers, the parts of chromosomes carrying the genes for ribosome synthesis. Chromosomes are present in the form of strings of DNA and histones (protein molecules) called chromatin. A nucleus, as related to genomics, is the membrane-enclosed organelle within a cell that contains the chromosomes. The nucleus (plural, nuclei) houses the cell s genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins.
