A researcher studying bacterial toxin predicts that a lysine within the toxin is important for binding it’s target cell. She used site-directed mutagenesis to change a codon for lysine (AAA) to one for asparagine (AAU). However, the mutant toxin still binds to its target cell just as well as the wild-type toxin bound and appears to have no other changes. This type of mutation is probably
