Nucleolus




 * //Nucleolus// **


 * Introduction **

Nucleolus, a bound structure that does not have a membrane. The nucleolus has proteins, and nucleic acids, which can be found inside the nucleus. Nucleolus's job is to transcribe, and to assemble RNA within itself.

**Structure** The major components of the nucleolus consists of three things, fibrillar centers, dense fibrillar components, and the granular components. The dense fibrillar components (DFC) or also known as pars fibrosa is consisted of a new transcribed RNA bound to ribosomal proteins. Pars granulosa, which is called granular components (GC) holds a RNA bound to ribosomal proteins that begins to assemble ribosomes.
