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. Long-term GLP-1 exposure drives phosphorylation of a key protein, resulting in massive changes in ...

While CRISPR may be the most notable genetic technology to emerge from microbes, many of the tools researchers use to control genes and their products are borrowed from bacterial systems. One of these ...

Because the β-galactosidase activity of exponentially growing cells is at steady state, the corresponding β-galactosidase synthesis rate is derived from Equation 2. The curves in Fig. 1 show that to a ...
