- Suppressor Mutations:
- Suppressor Mutation: A second mutation occurring at a distinct site from the primary mutation that partially or completely reverses or compensates for the mutant phenotypic effect, restoring the wild-type phenotype:
- Intragenic Suppressor: Occurs within the same gene (compensatory frameshift or secondary structure restoration).
- Intergenic / Extragenic Suppressor: Occurs in an entirely different gene (e.g., mutant tRNA reading through a nonsense codon).
- Correct Option: Option 3 (suppressor mutation).
