Mitoribosomes - The small subunit of the mitoribosome contains 1213S rRNA and the large subunit 16-17S rRNA. The RNA content of mitoribosomes is much less than that of cytoribosomes.
They contain only about half the RNA of bacterial ribosomes. Mitoribosomal RNAs have a comparatively low O+C content (30-40%), unlike most ribosomal RNAs. Mitochondrial RNA also generally has less secondary structure, as is shown by its relatively lower content of methylated bases, in comparison to other ribosomal RNAs.
