Nucleolus | Definition, Function, Ribosome, rRNA, Structure ...
nucleolus, spherical body within the nucleus of most eukaryotic cells, involved in the synthesis of ribosomal RNA (rRNA) and the formation of ribosomes. Nucleoli appear shortly after mitosis and form around specific repeating chromosome regions, known as nucleolar organizing regions, within the nucleus.
Nucleolus - Wikipedia
The nucleolus (/ nj uː ˈ k l iː ə l ə s, ˌ nj uː k l i ˈ oʊ l ə s /; pl.: nucleoli /-l aɪ /) is the largest structure in the nucleus of eukaryotic cells. [1] It is best known as the site of ribosome biogenesis. The nucleolus also participates in the formation of signal recognition particles and plays a role in the cell's response to ...
