WebThe chimeric tRNAs collectively introduced multiple sequence changes in all parts but the acceptor stem. However, although the acceptor stem in isolation (as the minihelix) lacked determinants for editing, ala-nyl-tRNA synthetase effectively cleared a mischarged amino acid from each chimeric tRNA. Thus, a covalently
