A bacterial histidine mutant was plated on minimal medium and a single colony grew. You decide to sequence the histidine biosynthetic gene of the revertant and discover that the original mutation is still present.  This colony must have been able grow due to a

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
