Bacterial Inactivation of Transforming Deoxyribonucleate [PDF]
Journal of Bacteriology, 1971 Competent and noncompetent bacteria are able to bind deoxyribonucleate (DNA). The consequence of this binding is different for the two types of bacteria. Competent bacteria are able to utilize the DNA for transformation. DNA exposed to noncompetent bacteria loses its biological activity with a coincident reduction in the double-stranded molecular ...

Reduced mutation rate and increased transformability of transposon-free Acinetobacter baylyi ADP1-ISx [PDF]
, 2017 The genomes of most bacteria contain mobile DNA elements that can contribute to undesirable genetic instability in engineered cells. In particular, transposable insertion sequence (IS) elements can rapidly inactivate genes that are important for a ...
