Recombinant DNA , molecules of DNA from two different species that are inserted into a host organism to produce new genetic combinations that are of value to science , medicine , agriculture, and industry. Since the focus of all genetics is the gene , the fundamental goal of laboratory geneticists is to isolate, characterize, and manipulate genes. Although it is relatively easy to isolate a sample of DNA from a collection of cells , finding a specific gene within this DNA sample can be compared to finding a needle in a haystack. Consider the fact that each human cell contains approximately 2 metres 6 feet of DNA. Therefore, a small tissue sample will contain many kilometres of DNA. However, recombinant DNA technology has made it possible to isolate one gene or any other segment of DNA, enabling researchers to determine its nucleotide sequence, study its transcripts, mutate it in highly specific ways, and reinsert the modified sequence into a living organism. The recombined DNA molecule is inserted into a host organism to produce new genetic combinations that are of value to science, medicine, agriculture, and industry.

NCBI Bookshelf. An Introduction to Genetic Analysis. New York: W. Freeman; Recombinant DNA is made by splicing a foreign DNA fragment into a small replicating molecule such as a bacterial plasmid , which will then amplify that fragment along with itself and result in a molecular clone of the inserted DNA.
