Ribosomal RNA

  • Chapter
The Ribonucleic Acids

Abstract

Ribosomes from all organisms are composed of two subunits which differ in size; each subunit contains an RNA species of high molecular weight and a variety of proteins. The larger of the two subunits contains, in addition, a low molecular weight RNA species, known as 5S RNA. In eukaryotes the cytoplasmic ribosome contains another small RNA component,1RNA, associated with the large subunit. This species appears to arise from cleavage of the high molecular weight ribosomal RNA precursor and, unlike 5S RNA, is hydrogen-bonded to the large ribosomal RNA in the ribosome. No such RNA has been found in the ribosomes of prokaryotes.
