nonsense codon — (= nonsense triplet) The three codons, UAA (known as ochre), UAG (amber) and UGA (opal), that do not code for an amino acid but act as signals for the termination of protein synthesis. Any mutation that causes a base change which produces a… … Dictionary of molecular biology

Nonsense mediated decay — (NMD) is a cellular mechanism of mRNA surveillance to detect nonsense mutations and prevent the expression of truncated or erroneous proteins. In mammals, NMD is triggered by exon junction complexes (EJC), which are initially deposited during pre … Wikipedia
Nonsense-mediated decay — (NMD) is a cellular mechanism of mRNA surveillance that functions to detect nonsense mutations and prevent the expression of truncated or erroneous proteins. Following transcription, precursor mRNA undergoes an assemblage of ribonucleoprotein… … Wikipedia
Nonsense mutation — In genetics, a nonsense mutation is a point mutation in a sequence of DNA that results in a premature stop codon, or a nonsense codon in the transcribed mRNA, and in a truncated, incomplete, and usually nonfunctional protein product. It differs… … Wikipedia
Nonsense mutation — A mutation (a change) in a base in the DNA that prematurely stops the translation (reading) of messenger RNA (mRNA) resulting in a polypeptide chain that ends prematurely and a protein product that is truncated (abbreviated) and incomplete and… … Medical dictionary
