IUPAC definition : An extrachromosomal genetic element consisting generally of a circular duplex of DNA
which can replicate independently of chromosomal DNA. R-plasmids are responsible for
the mutual transfer of antibiotic resistance among microbes. Plasmids are used as
vectors for cloning DNA in bacteria or yeast host cells.;
