at a glance Ribosomal RNA
Eukaryotic ribosomes are constructed from four types of ribosomal RNA. Three of these species (18S, 5.8S, and 28S) are derived from the processing of a single large precursor RNA, 45S rRNA, which is transcribed by RNA Polymerase I from tandem arrays of rDNA repeats. The remaining rRNA, 5S, is produced...
at a glance Ribosomal RNA
Ribosomal RNA genes (rRNA genes) are found as tandem repeating units in the nucleolus organizer regions of eukaryotic chromosomes. Each unit is separated from the next by a nontranscribed spacer. Each unit contains three regions coding for the 28S, 18S, and 5.8S rRNAs....

fundamentals Ribosomes (referenced by article RNA, Ribosomal)

Ribosomes provide the workshop and some of the tools for protein synthesis in all cellular organisms, including the subcellular organs, mitochondria, and chloroplasts. A yeast cell contains about 200,000-2,000,000 ribosomes. The chloroplastic ribosome genes are situated in the characteristic inverted...
fundamentals Ribosomal RNA
About 65% of the bacterial ribosomes are RNA. The 16S bacterial rRNA (1.54 kb) has short double-stranded domains and single stranded loops and about ten of the bases near the 3′-end are methylated. The 16S ribosomal RNA undergoes conformational changes (switches) before translation of the mRNA (Lodmell...
