The DNA necessary for bacterial life is usually in the chromosomal DNA. The plasmid DNA may confer benefits but the function of most plasmid DNA is currently unknown. Scientists have selected for plasmid free bacteria, and plasmid-free strains, especially E. coli, are available commercially.
They are most commonly found in bacteria as small, circular, double-stranded DNA molecules; however, plasmids are sometimes present in archaea and eukaryotic organisms. In nature, plasmids often carry genes that may benefit the survival of the organism, for example antibiotic resistance.lasmids can be transmitted from one bacterium to another (even of another species) via three main mechanisms: transformation, transduction, and conjugation. This host-to-host transfer of genetic material is called horizontal gene transfer, and plasmids can be considered part of the mobilome.
