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.
Plasmids. Plasmids are extra-chromosomal DNA molecules that can replicate in a cell separately from the chromosome. Frequently, plasmids have accessory genes that encode functions beneficial to the host cell. They are important for understanding how genes can be moved about between different bacteria and what that means for us. Originally identified in bacteria, plasmids have also been found in yeasts and other fungi. Most bacterial plasmids are circular, although some are linear, and they require at least an origin of replication to be maintained in the cell.
