| Description: A nonsense mutation in a protein-coding gene changes a codon for an amino acid into a stop codon, causing translation to terminate prematurely. Another mutation, in a tRNA gene, can circumvent the first mutation by altering the tRNA anticodon so that it will base-pair with the mutant mRNA. A functional protein is produced in this situation, even though suppression might not restore the original amino acid at that site.
