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.
A plasmid is a short, usually circular, and double-stranded segment of DNA that is found in the cytoplasm separate from the main bacterial chromosome. Plasmids usually contain between 5 and 100 genes that are not required for the survival of the bacteria.
