Nonsense suppressors change the effects of nonsense mutations by altering how stop codons are read. The largest class of nonsense suppressors are mutations in Category:tRNA genes that alter the codon-anticodon interaction to allow a stop codon to be read by that tRNA. This will only suppress the mutation if the amino acid inserted restores a functional protein product.
