RESUMO
Twenty-six spontaneous mutants at the ade3 locus of Saccharomyces cerevisiae have been mapped and characterized with respect to revertibility, osmotic remediability and temperature sensitivity. Twelve of the twenty-six are temperature sensitive, 25 of 26 are osmotic remedial and 21 of 26 revert. Two of the mutants map as deletions. At least five of the 26 are nonsense mutations but are also, unexpectedly, osmotic remedial. Three nonsense mutations are also temperature sensitive, again an unexpected result. The two multisite mutations are both temperature sensitive and osmotic remedial. For mutants at this locus osmotic remediability and temperature sensitivity cannot be considered diagnostic criteria for missense mutations.
