For example, repression of the lac operon by its repressor, called lacI, is inhibited by the ligand allolactose, to which the repressor protein directly binds. Thus, lactose, from which ...

An operon is defined as a functional unit of DNA that contains a group of genes under the control of same promoter. The lac operon in E. coli contains three structural genes, in addition to ...

Attenuation, or dampening, of the trp operon is made possible by the fact ... Translation therefore interferes with transcription, making this an example of translation-mediated transcription ...
