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 are often used as expression vectors in biotechnology. Plasmids are small, circular or linear pieces of DNA containing non-essential genes that are found in all â¦ life, although much more common in prokaryotes, especially bacteria.sually the plasmid also has an antibiotic resistance gene in addition to the target gene. This antibiotic resistance can be used to select for bacteria containing the plasmid. For example, the most common resistance gene is ampicillin resistance gene.
