- A nonsense mutation is a point mutation in a sequence of DNA that results in a premature stop codon in the transcribed mRNA12345. This stop codon does not code for an amino acid and leads to a truncated, incomplete, and possibly nonfunctional protein product12345. Nonsense mutations often cause a loss of function in the protein, as critical parts of the amino acid chain are no longer assembled4.Learn more:✕This summary was generated using AI based on multiple online sources. To view the original source information, use the "Learn more" links.In genetics, a nonsense mutation is a point mutation in a sequence of DNA that results in a nonsense codon, or a premature stop codon in the transcribed mRNA, and leads to a truncated, incomplete, and possibly nonfunctional protein product.en.wikipedia.org/wiki/Nonsense_mutationA nonsense mutation occurs in DNA when a sequence change gives rise to a stop codon rather than a codon specifying an amino acid. The presence of the new stop codon results in the production of a shortened protein that is likely non-functional.www.genome.gov/genetics-glossary/Nonsense-Mu…In biology, a nonsense mutation is a type of point mutation arising due to replication error and resulting in the generation of a nonsense codon/stop codon. This stop codon does not code for amino acid and leads to a protein product that is early truncated (shortened protein) and the resulting protein is thereby non-functional.www.biologyonline.com/dictionary/nonsense-mutati…Nonsense mutations are changes in DNA sequence that introduce a premature stop codon, causing any resulting protein to be abnormally shortened. This often causes a loss of function in the protein, as critical parts of the amino acid chain are no longer assembled.en.wikipedia.org/wiki/Stop_codonA nonsense mutation causes a pre-mature stop codon to appear in the gene, causing the protein to end its translation earlier than expected, resulting in a truncated copy of the protein. Nonsense mutation, usually leads to a genetic disorder.www.nonsensemutations.org/whatisnonsense
