Researchers at the University of Tsukuba have developed a vector that integrates the Cre enzyme gene with the specific DNA ...

A new study published in PLOS Genetics has identified an extreme mutational hotspot within the genome of Pseudomonas ...

Promoter sequences are DNA sequences that define where transcription of a gene by RNA polymerase begins. Promoter sequences are typically located directly upstream or at the 5' end of the ...

In addition, regulatory sites on prokaryotic DNA are typically located close to transcription promoter sites — and this plays an important part in gene expression. For an example of how this ...

Max Planck researchers discovered a 5,000-fold increase in the mutation rate in the genome of *Pseudomonas fluorescens*. The mutation regularly occurred in the promoter region of the *rpoS* gene and ...
