A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes.

Researchers made a “huge breakthrough” when they did an experiment “purely out of curiosity” which solves “a decades-long ...

An international collaboration has achieved an important breakthrough in understanding the genetic mechanisms that allow bacteria to build resistance to drugs.

A global team has made a significant advance in understanding how bacterial plasmids contribute to antibiotic resistance.

As part of the natural exchange, plasmids often provide recipient bacteria with genetic advantages. For example, many antibiotic-resistance genes spread through plasmid transfer between bacteria.

Fu and colleagues used Vibrio cholerae bacteria as a model for studying the plasmid defense system known as DdmDE, consisting of proteins called DdmD and DdmE, using cryo-electron microscopy to ...

A scaleable method for the liquid-phase separation of plasmid DNA from RNA. In the course of experiments on the potential of nucleic acid compaction for enhancement of chromatographic adsorption ...
