The nicked circular DNA and the reason it is termed as relaxed. Introduction: The plasmids are the most preferable genetic material to use in the recombinant DNA technologies and in genetic engineering studies. The plasmids are the extra circular DNA apart from the host DNA in many bacteria species like E.coli . The plasmids are easy to manipulate and are smaller in size to accommodate insertion of new genetic material. Hence, the plasmids are preferred for genetic engineering.
