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.
A 3D model of Neuron Cell Structure in Plasm.js. The cell is the structural and functional unit of living organisms. It answers three fundamental requirements: teleonomy, biogenesis and reproduction.nside there is another structure called nucleolus. The nucleolus is a region of the cell nucleus responsible for the synthesis of ribosomal RNA (rRNA). The nucleolus is not an organelle but a dense region of genetic material and protein.
