Nucleolus | Definition, Function, Ribosome, rRNA, Structure ...
网页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
网页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, which is the synthesis of ribosomes.
Nucleolus - Function, Difference Between Nucleus & Nucleolus
网页The nucleolus is the distinct structure present in the nucleus of eukaryotic cells. Primarily, it participates in assembling the ribosomes, alteration of transfer RNA and sensing cellular stress. The nucleolus is composed of RNA and proteins, which form around specific chromosomal regions.
The Nucleolus: Structure and Function - PMC
网页The nucleolus is the largest nuclear organelle and is the primary site of ribosome subunit biogenesis in eukaryotic cells. It is assembled around arrays of ribosomal DNA genes, forming specific chromosomal features known as nucleolar organizing regions (NORs) which are the sites of ribosomal DNA transcription.
