The nucleolus is the nuclear subdomain that assembles ribosomal subunits in eukaryotic cells. The nucleolar organiser regions of chromosomes, which contain the genes for preâribosomal ribonucleic acid (rRNA), serve as the foundation for nucleolar structure.
The nucleolus directs the assembly of proteins within the cell nucleus. The nucleolus is the part of the nucleus containing most of the genes that code for the synthesis of ri â¦ bosomal RNA (rRNA: the RNA molecules found in ribosomes).So rRNA is synthesized within the nucleolus.he Nucleolus is a 'nuclear organelle' inside of the eukaryotic Cell's nucleus. It's primary role is to synthesize messenger Rna which is rapidly exported, via the Nuclear Por â¦ es, to the nearly situated Ribosome peppered Rough Endoplasmic Reticulum.
