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.

"Sometimes, plasmids can integrate into genomic DNA, but this happens quite ... Argonaute proteins that trigger their host bacteria's death to avoid plasmid invasion. Argonautes, however, are ...

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

For example, many antibiotic-resistance genes spread through plasmid transfer between bacteria. However, bacteria also have numerous defense mechanisms aimed at eliminating any foreign DNA ...

An international collaboration has achieved an important breakthrough in understanding the genetic mechanisms that allow ...

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 ...

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

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

Initially, the agrobacterium cell contains a bacterial chromosome and a Tumor-inducing plasmid (Ti plasmid). The Ti plasmid is removed from the agrobacterium cell, and a restriction enzyme cleaves the ...
