Recombinant DNA (rDNA) technology is a technique that joins DNA molecules from different species. The resulting rDNA molecule is then inserted into a host organism to create new genetic combinations. These combinations can be useful in science, medicine, agriculture, and industry. Some examples of rDNA technology include DNA cloning and reproductive cloning. The steps involved in standard cloning protocols include: Choosing a host organism and cloning vector Preparing the vector DNA Preparing the DNA to be cloned Creating the rDNA Introducing the rDNA into the host organism  The...
