Schematic representation of A) secondary and B) tertiary structure of tRNA. Tertiary structure is based on the backbone of yeast tRNAAsp as in pdb model 1VTQ (Moras et al., 1980). The main parts of tRNA are highlighted in different colors, using darker colors for stems and lighter colors for loops. Used colors are red: acceptor stem, blue: deoxyuridine arm, gray: anticodon arm, cyan: variable arm, green: TΨC arm and orange: segments linking tRNA arms.
