| codon, nonsense | A codon that is not assigned to an amino acid or to any stop signal. It was originally thought that nonsense codons were synonymous with terminator codons (codon, terminator) in that they signaled termination of a protein chain. Recent studies have found this not to be true. (12 Dec 1998) |
|---|---|
| nonsense | As used in genetics, relating to a mutation that causes a sequence such that the growing peptide chain terminates, often after several incorrect amino acid residues are incorporated. (05 Mar 2000) |
| nonsense codon | <molecular biology> 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 nonsense codon results in premature termination of protein synthesis and probably a nonfunctional or nonsense protein. (13 Nov 1997) |
| nonsense mutation | <molecular biology> A mutation that causes a polypeptide chain to be ended prematurely. (13 Nov 1997) |
| nonsense strand | <molecular biology> DNA that does not code for part of a polypeptide chain or RNA.This includes introns and pseudo genes. In eukaryotes the majority of the DNA is noncoding. Noncoding strand refers to the so called nonsense strand, as opposed to the sense strand which is actually translated into mRNA. (18 Nov 1997) |
| nonsense suppression | Mutant tRNAs that read a chain termination codon as the signal for incorporation of a specific amino acid residue. (05 Mar 2000) |
| nonsense syndrome | <syndrome> A psychotic-like condition, without the symptoms and signs of a traditional psychosis, occurring typically in prisoners who feign insanity; e.g., such a person, when asked to multiply 6 by 4, will give 23 as the answer, or he will call a key a lock. See: malingering, factitious disorder. Synonym: nonsense syndrome, syndrome of approximate relevant answers, syndrome of deviously relevant answers. (05 Mar 2000) |
| nonsense triplet | A trinucleotide (codon) in which a base change to a termination codon results in premature termination of the growing polypeptide chain and, consequently, incomplete protein molecules, a termination codon. (05 Mar 2000) |
| amber suppressor | <molecular biology> A tRNA molecule which suppresses amber mutations because it has mutated to recognise the amber codon UAG (which normally signals that the translation of mRNA into an amino acid chain should stop) as a signal for inserting whatever amino acid it carries into the chain. As a result, it can prevent the amino acid chain from ending before it is completed. (09 Oct 1997) |
| genes, suppressor | Genes that inhibit expression of a previous mutation. They allow the wild-type phenotype to be wholly or partially restored. (12 Dec 1998) |
| genes, suppressor, tumour | Genes that inhibit expression of the tumourigenic phenotype. They are normally involved in holding cellular growth in check. When tumour suppressor genes are inactivated or lost, a barrier to normal proliferation is removed and deregulated growth is possible. (12 Dec 1998) |
| suppressor | A compound that suppresses the effects of mutation or suppresses what would be a normal course of events. (05 Mar 2000) |
| suppressor cell | <immunology> Lymphocyte class of cells suppressing T or B antigen dependent responses. (18 Nov 1997) |
| suppressor cells | Cells of the immune system that inhibit or help to terminate an immune response, e.g., suppressor macrophages and suppressor T-cells. Synonym: cytotoxic cell. (05 Mar 2000) |
| suppressor factor | <immunology> Factors released by T suppressor cells. See: suppressor mutation, ochre suppressor, opal suppressor. (19 Jan 1998) |
