WebWhole sonicated chromosomal DNA was also cloned in pUC18 as a population of control fragments. Seventy-one plasmids were labeled with 3H and tested for DNA binding, and the inserts of 28 of them were sequenced. The control plasmid pUC18 was absorbed to competent H. influenzae cells at low levels of 5 to 10% of DNA added. WebPlasmid is a double stranded, circular extra chromosomal DNA of bacterium. It is used in recombinant DNA experiments to clone genes from other organisms and make large quantities of their DNA. Plasmid can be transferred between same species or between different species. Size of plasmids range from 1-1000 kilo base pairs.
