What is the function of nucleolus in ribosomal RNA synthesis?
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. A single nucleus can house one to several ...

Feb 8, 2018 · The nucleolus is the most conspicuous domain in the eukaryotic cell nucleus, whose main function is ribosomal RNA (rRNA) synthesis and ribosome biogenesis. However, there is growing evidence that the nucleolus is also implicated in many other aspects of cell biology, such as regulation of cell cycle, growth and development, senescence ...
The nucleolus of several plant species has very high concentrations of iron in contrast to the human and animal cell nucleolus. Nucleolus Function. The nucleolus is considered as the brain of the nucleus, covering nearly 25% volume of the nucleus. Primarily, it takes part in the production of subunits that unites to form ribosomes.
- What is the function of nucleolus?Nucleolus helps in protein synthesis and production of the ribosome in the cells.
- Where is the nucleolus located in the cell?The nucleolus is located inside the nucleus of the eukaryotic cell. It is surrounded by a membrane inside the nucleus.
- What does the nucleolus contain?The nucleolus contains DNA, RNA and proteins. It is a ribosome factory. Cells from other species often have multiple nucleoli.
- Is nucleolus an organelle?The nucleolus is an organelle, and a very unusual one because it is devoid of lipid bilayers, which are characteristic of other organelles.
- What would happen if there is no nucleolus in the cell?If the nucleolus didn’t exist, there would be no production of ribosomes and there would be no synthesis of proteins.
The primary function of the nucleolus consists in ribosomal RNA (rRNA) transcription, rRNA processing and ribosome subunit assembly (Hernandez-Verdun et al. 2010; Pederson 2011; Raska et al. 2006 ).

Nucleolus Function. The nucleolus (nucleoli, plural) is one of the most important components of the cell nucleus, and is far the most easily recognized substructure in the nucleus of eukaryotic cells. It can easily be determined by phase contrast microscopy and with the use of different dyes.

The main function of the nucleolus is the synthesis and processing of rRNA and ribosome assembly. Nucleoli contain clusters of ribosomal RNA genes (rDNA) and their transcripts (rRNA) (reviewed in [ 1. ]), as well as several hundred proteins participating in many nuclear processes inside and outside the nucleolus [ 2. ].
