mutant phenotype evidence deletion mutation phenotypic evidence ECO:0005510 ECO:0001038 In contrast, and in full agreement with the previous results of Wade et al. (17), the longer deletion in the TB23 fragment, that removes MelR binding site 2, results in a sharp reduction in the repression of the melR promoter by MelR. The length of the DNA deleted can range from a single nucleotide to enough material that could include multiple genes. eco As a child of 'experimental phenotypic evidence', this is not to be confused with the biological processes deletion mutation / deletion deficiency in which DNA is lost during DNA replication. Contrast with knockout phenotypic evidence in which any number of changes to the DNA result in elimination of the function of the gene in question. mchibucos SIB:PG 2014-03-16T11:30:54Z A type of mutant phenotype evidence resulting from a mutation in which there is the removal of one or more contiguous nucleotides that may result in altered function or other measurable properties. deletion mutation evidence
