The nucleolus is a distinct structure in the nucleus of the cell composed of filamentous and granular material. It is the site of synthesis and processing of ribosomal RNA and the assembly of this RNA with ribosomal proteins into ribosomal subunits.
Present in the nuclear matrix, the nucleolus is not surrounded by a membrane. The main components of nucleolus are ribonucleic acid (RNA), deoxyribonucleic acid (DNA) and proteins. The nucleolus function and structure can be understood with the help of information provided below.
