Recombinant DNA technology enables individual fragments of DNA from any genome to be inserted into vector DNA molecules, such as plasmids, and individually amplified in bacteria. Each amplified fragment is called a DNA clone.he vector molecules with their inserts are called recombinant DNA because they consist of novel combinations of DNA from the donor genome (which can be from any organism) with vector DNA from a completely different source (generally a bacterial plasmid or a virus).
The Mississippi River begins in Lake Itasca in Minnesota, flows through the middle of the continental United States and finally ends in the Gulf of Mexico. At 2,350 miles long, it is the third-longest river in North America.
