Plasmids used in recombinant DNA technology often have several key features: they usually possess a gene for antibiotic resistance to select for cells that have taken up the plasmid, replicate independently of the host genome allowing for the amplification of the inserted gene, are typically circular double-stranded DNA molecules for stability and ease of insertion of foreign DNA, and often contain reporter genes to identify successful incorporation of the desired gene.
