WebThe nucleolus (/njuːˈkliːələs, -kliˈoʊləs/, plural: nucleoli /-laɪ/ ) is the largest structure in the nucleus of eukaryotic cells. It is best known as the site of ribosome biogenesis. Nucleoli also participate in the formation of signal recognition particles and play a role in the cell's response to stress. Nucleoli are made of proteins, DNA and RNA and form around … The nucleolus also participates in the formation of signal recognition particles and plays a role in the cell's response to stress. [2] Nucleoli are made of proteins, DNA and RNA, and form around specific chromosomal regions called nucleolar organizing regions. Meer weergeven The nucleolus is the largest structure in the nucleus of eukaryotic cells. It is best known as the site of ribosome biogenesis, which is the synthesis of ribosomes.
