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.
Map the Mississippi Watershed! Teacher Notes: 2. The Mississippi Watershed is all the land area that drains into the Mississippi River. On the map the watershed (or âbasinâ) boundary is indicated by the dashed line that encircles all Mississippi River tributaries. 4. By definition the Mississippi River starts at Lake Itasca in northern Minnesota. However, it can also be said that the Mississippi River starts wherever rain or snow falls in the Mississippi Watershed, because water that flows from land anywhere in the watershed will eventually flow into the Mississippi River. (This is a good point for discussion.) 8. St. Louis 10. The length of the Mississippi River is approximately 2,350 miles.
