| constitutive mutant | An organism with a mutation in a regulatory gene, so that the genes which its flawed regulatory product are supposed to suppress become constitutive genes, or impossible to turn off. Thus, the products of the uncontrolled genes are produced to excess. (09 Oct 1997) |
|---|---|
| homeotic mutant | <molecular biology> A mutant in which one body part, organ or tissue, is transformed into another part normally associated with another segment. Examples are the antennapedia and bithorax mutants of Drosophila. (18 Nov 1997) |
| host range mutant | A mutant of phage or animal virus that grows normally in one of its host cells, but has lost the ability to grow in cells of a second host type. (18 Nov 1997) |
| silent mutant | A mutant that is not phenotypically manifest. Synonym: silent mutant. (05 Mar 2000) |
| suppressor-sensitive mutant | A conditionally lethal, host range, bacteriophage mutant that produces nonsense codons and can replicate only in a host bacterium able to translate the nonsense codon; the mutation's effects are lethal (i.e., prevent replication of the virus) in a bacterium without such a suppressor mechanism. (05 Mar 2000) |
| deficiency mutant | Mutant with a nutritional requirement not present in the wild type organism. Synonym: defective organism, deficiency mutant. (05 Mar 2000) |
| disjunction mutant | Drosophila mutant in which chromosomes are partitioned unequally between daughter cells at meiosis, as a result of nondisjunction. (18 Nov 1997) |
| inactive mutant | A mutant that is not phenotypically manifest. Synonym: silent mutant. (05 Mar 2000) |
| quick-stop mutant | A bacterial mutant that ceases replication immediately when the temperature reaches a certain level. Compare: temperature-sensitive mutant. (05 Mar 2000) |
| temperature-sensitive mutant | A viral mutant that is able to replicate at one portion of a temperature range but not at another, the parent (wild type) strain being able to replicate over the whole temperature range. Compare: cold-sensitive mutant, quick-stop mutant. (05 Mar 2000) |
| uninducible mutant | A mutant that cannot be induced. (05 Mar 2000) |
| mutant |
Of an organism, population, gene, chromosome, etc.: Differing from the corresponding wild type by changes in one or more loci. (16)

| mutant |
Mutations are changes in the nucleotide sequence of the genome (affecting genes) and the resulting changes in the amino acid sequence of proteins. The amino acid sequence of proteins determines their structure and function, the latter being subject to natural selection. Mutation occur in different forms, from single nucleotide mutations to insertions and deletions of longer sequences as well as gene duplications, deletions and chromosomal rearrangements in higher organisms.
