They chemically converted the cysteine on tRNA.Cys molecules to alanine in vitro. This Ala-tRNA.Cys was used to synthesize hemoglobin, which normally contains a cysteine on each ? and ß chain. The resulting hemoglobin molecules contained alanine at the position normally occupied by cysteine, which indicated that the tRNA had read the cysteine codon and inserted the alanine it carried.
