Comments "tRNAs bear the most chemically diverse modifications among all types of nucleic acid entities: the presence of modified nucleotides in tRNA is 10-fold more than in the most abundant biological RNA, ribosomal RNAs (rRNAs), and in total 17% of the tRNA nucleotides are modified (primary sources). These modifications play an important role and affect both structure and function of tRNAs. Modified nucleotides in the anticodon loop and some more distant to the anticodon loop affect the fidelity of decoding (Schmeing et al ., 2011 & 2nd primary source). Modifications of nucleotides at position 34 alter the classical Watson-Crick pairing and allow one tRNA species to read more than one codon (Crick, 1966 Agris, 1991 Agris et al .,2007)."
