Bottom left: Engineered genetic code of Ec_Syn61Δ3. Missing codons, anticodons, and genes are marked with dashed lines. Remaining codons, anticodons, and genes are marked with bold lines. Bottom right: Schema of central dogma of biology including our observation. c , Relative escape rate [(cfu/mL)/(cfu/mL)] defined as the number of colonies formed by Ec_Syn61Δ3 with (+) and without (-) the wild-type plasmid pUC57 relative to those of parallel experiments with pUC57-dTCR upon selection onto carbenicillin-containing agar plates ( n = 4 ). Escapees of Ec_Syn61Δ3 without the pUC57 plasmid were not detected (ND) onto carbenicillin-containing agar plates with up to 1 mL of OD 600 plated (Methods). The dashed bar length represents the ratio of 10 -9 cfu/mL and measured number of cells of Ec_Syn61Δ3 with pUC57-dTCR ( n = 4 ). d , Number of colonies formed by Ec_Syn61Δ3 escapees with selected plasmids including TCR-containing antibiotic resistance genes upon selection onto antibiotic-containing agar plates (mean ± standard deviation (SD), n = 2-4 ). The table below describes the number of TCR codons, plasmid copy number, presence of a his-tag on the antibiotic resistance protein, and antibiotic resistance for each plasmid. High or low plasmid copy number is denoted by + or -. Presence or absence of a His-tag is denoted by + or -. Antibiotic resistance acronyms: ChlR, <t>chloramphenicol;</t> KanR, kanamycin; AmpR/CarbR, ampicillin/carbenicillin; SpecR, spectinomycin; and GentR, gentamicin.
