Video of DNA: mutations | Britannica

The amino acid sequence of part of a protein has been determined: N... Gly Ala Pro Arg Lys ... C A mutation has been induced in the gene encoding this protein using the mutagen proflavin. The resulting mutant protein can be purified and its amino acid sequence determined. The amino acid sequence of the mutant protein is exactly the same as the amino acid sequence of the wild-type protein from the N terminus of the protein to the glycine in the preceding sequence. Starting with this glycine, the
