Detailed explanation-1: -Eukaryote ribosomes are produced and assembled in the nucleolus. Ribosomal proteins enter the nucleolus and combine with the four rRNA strands to create the two ribosomal subunits (one small and one large) that will make up the completed ribosome (see Figure 1).
Detailed explanation-2: -Nucleoli are present in almost every eukaryotic cell type and represent the most prominent compartment of the cell nucleus. 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.
Detailed explanation-3: -The primary function of the nucleolus is in facilitating ribosome biogenesis, through the processing and assembly of rRNA into preribosomal particles.
