According to this model, sigma (σ) factors bind to RNA polymerase to initiate transcription—the process by which genetic information is copied from DNA to RNA—and then detach after initiation to allow ...

When E. coli detects damage to its genetic material, it sends out an SOS signal that alters activity inside the cells. "The bacteria go into full emergency mode," says PhD candidate Olaug Elisabeth ...

Gram-negative bacteria like E. coli have built-in gatekeepers, porins, and pumps that decide what gets in or out, including antibiotics. The bacteria's genetic control room tightly regulates these ...

The study analysed 94 different chemical substances to understand their influence on bacterial behaviour. Here is everything you need to know.

A new study overturns a central textbook model of bacterial gene regulation and unveils new paths for understanding bacterial gene regulation and its evolution. This could help designing better ...

Much of the phenotypic variation that is observed within and between species is the result of differences in gene regulation: specifically when, where and how much the genes are expressed. Given the ...

Indian scientists have helped overturn a 50-year-old model explaining how bacteria regulate their genes, challenging a foundational concept in molecular biology.

A cell-free genomics approach silences cellular noise and reveals transcription drivers, improving our understanding of a ...

After two recent major recalls for organic walnuts and ground beef found to be potentially contaminated with E. coli, interest in symptoms and prevention for the disease is on the rise. E. coli is ...
