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 ...

How do bacteria avoid wasteful production of unnecessary proteins when their genes are always on? The answer lies in regulating the operon. As trp levels increase, trp binds to trpR, causing a ...

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 ...

The 92-year-old bacterial geneticist who helped pioneer the study of gene regulation has passed away. A series of rodent experiments showed that even with abundant food and water, personal space is ...
