Question
An investigator was interested in studying UAG nonsense suppressor mutations in bacteria. In one species
of bacteria, she was able to select two different mutants of this type, one in a tRNATyr gene and the other
in a tRNAGln gene, but in a second species, she was
not able to obtain any such nonsense suppressor mutations, even after very extensive effort. What could
explain the difference between the two species?
