<prompt> A mutation that converts an amino acid codon to a stop codon is a:Nonsense mutationTransversionSilent mutationFrame shift mutation  <response>: Changes one codon for an amino acid into another codon for that same amino acid - Silent mutationCodon for one amino acid is changed into a codon of another amino acid - Missense mutationCodon for one amino acid is changed into a translation termination codon - Non-sense mutationReading frame changes downstream to the mutant site - Frameshift mutation.A purine base replaced by another pyrimidine, or pyrimidine replaced by another purine -Transversion.Key ConceptNonsense mutationA coding codon mutated to a nonsense codon result in premature termination of polypeptide chain.
