The genes and important sequences for the regulation of the lac operon are organized such that several mediators can fine tune expression of the three genes in the operon itself— lacZ, lacY, and lacA.

Last week I finally addressed promoters and gave a bit of background on the lac operon. Looking back, I feel that I didn't give the topic of operons adequate treatment. They are a very crucial aspect ...

New research suggests a possible explanation for the organization of operons, jointly controlled clusters of genes that evolved in bacterial chromosomes. Operons, which are found in the chromosomes of ...

The 92-year-old bacterial geneticist who helped pioneer the study of gene regulation has passed away. The organizers of the American Diabetes Association meeting had a group of researchers removed ...
