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 ...

1). In the 'off' state, the Lac inhibitor represses the lac operon, which prevents expression of the Tet repressor and the target gene. Additionally, a short hairpin RNA (shRNA) against the target ...

Shelby is an assistant editor for The Scientist. She earned her PhD from West Virginia University in immunology and microbiology and completed an AAAS Mass Media fellowship.

With synthesis costing perhaps $0.11 per base, researchers rarely think twice before ordering a few 30-mer PCR primers. But what if your goal is the synthesis of an entire gene, operon, or even genome ...

Gut microbial metabolism of L-carnitine, leading to the production of trimethylamine N-oxide (TMAO), links red meat ...

In particular, the 'polycistronic operon' system, where multiple genes are expressed in coordination to form complexes and perform specific functions, is crucial in maximizing encoding efficiency ...

Eurofins MWG Operon has expanded its exome sequencing services with the Ion Proton Next Generation Sequencer. Certification for Ion ...
