A second mutation that occurs at a different site from the first mutation, and which returns the mutant back to the wild-type phenotype, is a(n) mutation.

The restoration of function by a second mutation at a different site in the same gene is called back mutation. conditional lethality. intragenic suppression. intergenic suppression.

The change of an amino acid codon to one of the termination codons is called an antimutator mutation. a missense mutation. a frameshift mutation. a nonsense mutation. The restoration of function by a second mutation at a different site in the same gene is called back mutation. conditional lethality. intragenic suppression. intergenic suppression. The temperature at which a temperature-sensitive mutant is viable is called the melting point. tautomeric temperature. permissive temperature. restrictive temperature.

A mutant strain of haploid yeast must be supplemented with adenine to grow. You grow some of this yeast on a complete media plate and replica plate onto media without adenine. You find one colony that can grow without adenine. You mate the colony that can grow without adenine to a different wild-type strain and let it undergo meiosis. All of the progeny yeast can grow on media without adenine. Which of the following statements is most likely to be TRUE? The sequence in the gene that was originally mutated was restored to the wild-type sequence. The yeast had a second mutation in a different protein that restored a necessary protein-protein interaction The yeast acquired a mutation in a tRNA anticodon that allowed functional protein to be produced The gene that was mutated originally acquired a second mutation in that same gene that allowed a functional protein to be made.
