plasmid

plas·mid [ plázmid ] (plural plas·mids)


noun 
Definition:
 
small independent circle of DNA: a small circle of DNA that replicates itself independently of chromosomal DNA, especially in the cells of bacteria. Plasmids often contain genes for drug resistance and are used in genetic engineering, since they can be transmitted between bacteria of the same and different species.
