Plasmids are small circular dna molecules found in bacteria that replicate separately from chromosomes. why are plasmids essential for recombinant dna technology? plasmids are able to rapidly reproduce exact copies of cells, so they provide a means to acquire a large number of cells that contain a particular gene of interest. dna from a gene of interest can be inserted into a plasmid, then the modified plasmid can be inserted into a bacterial cell to replicate a gene of interest many times. plasmids can cleave the sugar–phosphate bonds in dna molecules in a staggered manner, creating single‑stranded, "sticky" ends of dna where the gene of interest can attach. plasmids provide the catalytic action required to denature a molecule of dna from a gene of interest that can be used in recombinant dna technology.
