All classes of RNA transcripts must be processed into mature species. The reactions include several types: Nucleolytic cleavage, as in the separation of the mature rRNA species from the primary transcript of RNA polymerase I action; Chain extension (non‐template‐directed), as in the synthesis or regeneration of the common CCA sequence at the 3′ end of transfer RNAs or of PolyA at the 3′ end of mRNAs; and Nucleotide modification, for example, the synthesis of methylated nucleotides in tRNA or rRNA. These reactions are a feature of both prokaryotic and eukaryotic gene expression, and the biological consequences are diverse. For example, modified nucleotides can affect the way in which a tRNA recognizes different codons.
