Related to conjugative plasmid: conjugation, R plasmid


A circular, double-stranded unit of DNA that replicates within a cell independently of the chromosomal DNA. Plasmids are most often found in bacteria and are used in recombinant DNA research to transfer genes between cells.


(Genetics) a small circle of bacterial DNA that is independent of the main bacterial chromosome. Plasmids often contain genes for drug resistances and can be transmitted between bacteria of the same and different species: used in genetic engineering
[C20: from plasm + -id1]


(ˈplæz mɪd)

a strand or loop of DNA that exists independently of the chromosome in bacteria and yeast and that is capable of genetic replication: used in recombinant DNA procedures as a vehicle of gene transfer.
