21. Substrates of the exosome include messenger RNA, ribosomal RNA , and many species of small RNAs. 22. In the cytoplasm, ribosomal RNA and protein combine to form a nucleoprotein called a ribosome. 23. SNORD99 is predicted to guide the 2'O-ribose methylation of 28S ribosomal RNA at residue A2774. 24. Role of precursor sequences in the ordered maturation of E . coli 23S ribosomal RNA . 25. It can be identified by 16S ribosomal RNA sequencing, and is associated with bacterial vaginosis. 26. Their ribosomal RNA genes are 96.3 % identical. 27. Dugesiidae and Geoplanidae share a duplication of the cluster that codifies for the 18S ribosomal RNA . 28. Comparison of ribosomal RNA genes has provided a phylogeny of known strains within " Chlamydiae ". 29. Other types of RNA include ribosomal RNA ( rRNA ) and transfer RNA ( tRNA ). 30. This snoRNA was originally cloned from human ribosomal RNA ( rRNA ) at residue A99 3
