The lac operon won't be transcriptionally active in the presence of lactose. The lac operon will be translated if lactose is not present.

<h3>What is mutation?</h3>

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.

<h3>What is the function of the lac repressor?</h3>

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.

<h3>What is allolactose?</h3>

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.

Serggg [28]

To avoid this kind of behavior companies should appoint only educated and talented persons having self-respect after taking interviews. When a company recruits the managers, it is company duty to train their employees in professional ethics and teach them a proper way of doing a job with self-respect. Higher authorities should demoralize them with this kind of soapy behaviors.
