Wild-type strains of E. coli have a tRNA with a 5′-GUA-3′ anticodon that recognizes the UAC codon for tyrosine. We can represent this tRNA as GUA-tRNATyr.
Suppose you isolated a strain of E. coli in which a mutation changed the anticodon in this tRNA to 5′-CUA-3′ (creating CUA-tRNATyr). Answer the following questions about translation elongation in each strain.
