nonsense mutation
a mutation that changes a codon from one that specifies an amino acid into one that does not; there are three such nonsense codons

Nonsense Mutation
A nonsense mutation is the substitution of a single base pair that leads to the appearance of a stop codon where previously there was a codon specifying an amino acid.
Nonsense mutations
With a nonsense mutation, the new nucleotide changes a codon that specified an amino acid to one of the STOP codons (TAA, TAG, or TGA).
Nonsense mutation
A mutation which replaces a codon for an amino acid with a codon for chain termination (UAG, UAA, or UGA).
nonsense mutation
A mutation that changes an amino acid codon to one of the three stop codons, resulting in a shorter and usually nonfunctional protein.

Nonsense mutation A point mutation which alters a codon so that instead of coding for an amino-acid it codes for a translation stop signal.

Main article: Nonsense mutation
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 possibly a truncated, ...
Nonsense mutation
Mutation that changes a codon or an amino acid to a termination or stop codon and leads to premature termination of translation.

Silent, Missense, and Nonsense Mutations
Three kinds of point mutations can occur. A mutation that results in an amino acid substitution is called a missense mutation.
Humans have 347 functional odor receptor genes; the other genes have nonsense mutations. This number was determined by analyzing the genome in the Human Genome Project; the number may vary among ethnic groups, and does vary among individuals.
A mutation that affects the transcription or translation of part of the gene or operon downstream of the mutant site. For example, nonsense mutations, frameshift mutations, and insertion sequence(IS)-induced mutations.
Nonsense mutation -- a mutation in which a codon is changed to a stop codon, resulting in a truncated protein product.
