The most widely understood role of RNA is in protein synthesis, which includes messenger RNA (mRNA), transfer RNA (tRNA) and ribosomal RNA (rRNA) (see Chapter 2). 13). Indeed the “RNA world” hypothesis suggests that the original enzymes were all RNA and that protein only assumed this role later in evolution. The backbone of RNA is formed by 3′, 5′-phosphodiester bonds, the sugar is ribose, and the nucleobase is thymine. Ribosomal ribonucleic acid (rRNA) is a type of non-coding RNA which is the primary component of ribosomes, essential to all cells. Chuba, P. J., Pelz, K., Krekeler, G., De Isele, T. S., and Gobel, U., 1988, Synthetic oligodeoxy-nucleotide probes for the rapid detection of bacteria associated with human periodontitis. Weisburg, W. G., Barns, S. M., Pelletier, D. A., and Lane, D. J., 1991, 16S ribosomal DNA amplification for phylogenetic study, Weiss, J. RNA processing sometimes requires other RNA molecules, either as guides or as actual enzymes—ribozymes. In these cases, the original RNA molecule, before any further processing occurs, is known as the primary transcript. The term hnRNA (heterogeneous nuclear RNA) was also used previously, before the relationship of precursor RNA to the final processed RNA product was understood. DeLong, E. F., and Shah, J., 1990, Fluorescent, ribosomal RNA probes for clinical application: A research review.

Gouy, M., and Li, W.-H., 1989, Phylogenetic analysis based on rRNA sequences supports the archaebacterial rather than the eocyte tree. The phylogenetic analysis of full-length small-subunit ribosomal RNA (18S rRNA) genes has revealed five clades within the order Piroplasmidora. These RNAs are involved both in sequence recognition and in the actual chemical reactions of cutting and splicing. In other, related cases, several RNA molecules are included in the same primary transcript, which is then cleaved into several parts. Advances in molecular biology are now providing the means for solving long-standing problems in microbiology. Olsen, G. J., 1988, Phylogenetic analysis using ribosomal RNA. Its abundance can mask the other types of RNA, and therefore, rRNA must be removed. Only a few years after the initial rRNA-based phylogenetic observations were published (Woese and Fox, 1977), the 16S rRNA molecule was used to characterize Prochloron, an uncultivated symbiont of marine invertebrates (Seewaldt and Stackebrandt, 1982), and the smallest ribosomal RNA molecule, 5S rRNA, was used to analyze the composition of a few simple microbial communities (Stahl et al., 1984, 1985; Lane et al., 1985b). To ensure that the RNA sample is free of degradation and contamination, a small amount of the sample may be analyzed using lab-on-a-chip methods (see Chapter 8: DNA Sequencing). We report a multi-centre study focused on the analysis of rRNA processing of 53 Italian DBA patients using capillary electrophoresis analysis of rRNA maturation of the 40S and 60S ribosomal subunits. However, as shown later, more complex RNA processing involves other RNA molecules. Historically the function of RNA in the cell was to assist in the translation of genetic information from DNA into protein. It is also known as community fingerprinting.

Most RNA samples are obtained from one or more cells of interest by isolating RNA. RNA polymerase III promoters differ significantly from RNA polymerase II promoters in that they are located downstream from the transcription start site and within the transcribed segment of the DNA. RNA processing can be divided into cutting/joining RNA segments or base alteration of the ribonucleotides. van Niel, C. B., 1949, The “Delft School” and the rise of general microbiology. Olsen, G. J., 1987, Earliest phylogenetic branchings: Comparing rRNA-based evolutionary trees inferred with various techniques.
