title: Archetypical features in tRNA families.
abstract: A compilation of known tRNA, and tRNA gene sequences from archaebacteria, eubacteria, and eukaryotes permits the construction of tRNA cloverleafs which show conserved structural elements for each tRNA family. Positions conserved across the three kingdoms are thought to represent archetypical features of tRNAs which preceded the divergence of these kingdoms.
