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 ...

Paralogues are duplicated genes that reside at different genomic locations but play interconnected roles in a common biological process. Taking advantage of their overlapping expression pattern during ...

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. The organizers of the American Diabetes Association meeting had a group of researchers removed ...
