Quizplus · Accepted Answer

A suppressor mutation is one that overcomes the effect of another mutation, often by changing another amino acid to compensate for the change caused by the first mutation. A nonsense suppressor specifically allows for translation to continue past a premature stop codon caused by a nonsense mutation, but this is not what is being described in the question. Amber mutation refers specifically to a type of nonsense mutation where a mutation occurs at a specific nucleotide causing a premature stop codon.
