Figure 1From: Transfer RNA modifications and genes for modifying enzymes in Arabidopsis thalianaModified nucleosides in eukaryotic tRNAs and chemical structures. A: Clover-leaf structure of eukaryotic tRNA. Each circle represents a nucleotide, numbered from 5'- to 3'- end. Modified nucleosides found at different positions are shown. B: Chemical structures of some modified nucleosides.Back to article page
