The lac operon won't be transcriptionally active in the presence of lactose. The lac operon will be translated if lactose is not present.
In biology, a mutation is defined as a change in the nucleic acid sequence of a virus, extrachromosomal DNA, or an organism. Viral genomes can either be made of DNA or RNA.
The LacI repressor protein stops the transcription of the lac genes, which are essential for lactose utilisation in E. coli. LacI makes use of several operators, like many other repressors, to boost repression effectiveness.
An analogous disaccharide to lactose is allolactose. As opposed to lactose, which has a 1-4 linkage, it is made up of the monosaccharides D-galactose and D-glucose joined through a 1-6 glycosidic linkage. It might result from sporadic -galactosidase transglycosylation of lactose.
