Explanation:
Detailed explanation-1: -The nucleolus is a spherical structure found in the cell’s nucleus whose primary function is to produce and assemble the cell’s ribosomes. The nucleolus is also where ribosomal RNA genes are transcribed.
Detailed explanation-2: -At the nucleolus, a long ribosomal RNA (rRNA) precursor molecule is transcribed from DNA, processed into three mature RNAs, and packaged together with specific proteins to make the large and small ribosomal subunits.
Detailed explanation-3: -The primary function of the nucleolus is in facilitating ribosome biogenesis, through the processing and assembly of rRNA into preribosomal particles.
