The soma is enclosed by a membrane which protects it, but also allows it to interact with its immediate surroundings. As the nucleus regulates the integrity of genes and gene expression, it is also referred to as the control center of a cell. (b) Describe its function. Thirteen of these genes provide instructions . The nucleolus is the ribosome factory of the cells. See all questions in Organelles in Eukaryotic Cells. 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 cells volume. Once in the cytoplasm, ribosomes and another RNA molecule called transfer RNA work together to translate mRNA in order to produce proteins. 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.
