Plasmids are small, circular extra fragments of DNA, commonly found in bacteria that are capable of replicating independent of the host genome, though plasmids are not required for survival of a living organism. But encodes essential genetic determinants that enable an organism to adapt and resist unfavourable conditions for better survival. Rolling circle, Col E1 type and iteron-containing replicons are the common modes through which plasmid replicates, each mechanism with unique significance to the organism.
