... Analysis Plasmid DNA is the extrachromosomal DNA present in the bacteria. This plasmid DNA is able to carry the insert genes with it, and these genes are able to express themselves in the bacteria. When a gene is inserted into the Plasmid DNA, it is called Recombinant DNA. Restriction mapping is the process of cutting the Plasmid DNA using the restriction enzymes, and they also give us the idea whether the gene of interest is present in the correct position or not. White plasmid DNA was found to contain three restriction sites, of which two are for Hind III, and one site is for Sac I. The blue plasmid DNA did not contain any of the restriction sites for Hind III or Sac I. Introduction Plasmids are...
