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 new study published in PLOS Genetics has identified an extreme mutational hotspot within the genome of Pseudomonas fluorescens, providing unprecedented insight into the relationship between gene ...
Forbes contributors publish independent expert analyses and insights. GrrlScientist writes about evolution, ecology, behavior and health. Once hailed globally as “miracle drugs”, antibiotics have ...
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 ...
In 1943, two scientists named Max Delbrück and Salvador Luria conducted an experiment to show that bacteria can mutate randomly, independent of external stimulus, such as an antibiotic that threatens ...
