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.

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 ...

and resides on a DNA plasmid called pGLO. The pGLO plasmid also contains a gene encoding for beta-lactamase. Beta-lactamase is an enzyme that will allow transformed bacteria to be resistant to ...
