Thus far, you have determined that the mutagen chemically alters a single base in such a way that its base-pairing properties are altered permanently. To determine the specificity of the alteration, you examine the amino acid changes that take place after mutagenesis. A sample of what you find is shown here:Original: Gln–His–Ile–Glu–LysMutant: Gln–His–Met–Glu–LysOriginal: Ala–Val–Asn–ArgMutant: Ala–Val–Ser–ArgOriginal: Arg–Ser–LeuMutant: Arg–Ser–Leu–Trp–Lys–Thr–Phearrow_forward
