What would be the consequence of a mutation in a bacterial cell that produces a defective aminoacyl-TRNA synthetase that attaches a lysine instead of the normal phenylalanine to TRNAS with the anticodon AAA? The cell will compensate for the defect by attaching phenylalanine to tRNAs with lysine-specifying anticodons. None of the proteins in the cell will contain phenylalanine. Proteins in the cell will include lysine instead of phenylalanine at amino acid positions specified by the codon UUU. O The ribosome will skip a codon every time a UUU is encountered. Figure 5.
