Recombinant DNA is an artificial form of DNA that cannot be found in natural organisms. It is made in the laboratory by joining together genes taken from different sources. This is done by selecting and cutting out a gene at a specific point on a strand of DNA using restriction enzymes which act as molecular scissors.
Recombinant DNA is a type of DNA that is artificially created by inserting a strand or more of DNA into a different set of DNA. It is used in genetic modification to create completely new organisms by adding artificial bits or bits of DNA from other organisms to an existing creature. The term is often shortened to rDNA.
