To do this, Julie Laurent irradiated the bacterial cells with UV-C light, which damages random points of the bacterial DNA. She then placed the bacteria in a dark room to prevent any repair of the DNA ...

A 'silent' mutation in the genetic code of bacteria has been discovered by UK researchers, offering hope for future microbial treatments. The authors of new research, published in the Proceedings of ...

The Mfd protein repairs bacterial DNA, but can also, to scientists' surprise, promote mutation. Bacterial mutations can lead to antibiotic resistance. Understanding this second "role" of the Mfd ...

Scientists in the Netherlands, U.K., and U.S. report on study results suggesting that a common strain of Escherichia coli gut bacteria could be contributing directly to bowel cancer by releasing a ...
