The FY strain was transformed with one of the plasmids harboring the test sequence as indicated (from 5′ to 3′). Frameshifting efficiencies were measured at 30°C, and the data are expressed as percentages. Codons including the dinucleotides are underlined and anticodon of tRNA anticodon loops are in bold (Lecointe, 2002); heptamers are in bold and dinucleotides in uppercase.
