Recombinant DNA

As recombinant DNA, an artificial DNA molecule is called, which was re-assembled in vitro, by means of genetic engineering methods ( restriction and ligation ). The DNA can originate from different organisms or synthesized in vitro, either chemically by means of oligonucleotide synthesis, or enzymatically by the polymerase chain reaction (PCR). A recombinant protein via recombinant DNA, but not all recombinant DNA encodes for a protein automatically.

An example of recombinant DNA plasmids, which are initially isolated from bacterial cells, and then incorporates it into a transgene from other organisms, or of an artificial gene synthesis. See also vectors in genetic engineering.

Recombinant DNA was generated for the first time in 1973 by the Americans Herbert W. Boyer and Stanley N. Cohen.
