n. Abbr. rDNA
Genetically engineered DNA prepared by transplanting or splicing genes from one species into the cells of a host organism of a different species. Such DNA becomes part of the host's genetic makeup and is replicated.
(Genetics) genetics DNA molecules that are extracted from different sources and chemically joined together; for example DNA comprising an animal gene may be recombined with DNA from a bacterium
DNA in which one or more segments or genes have been inserted, either naturally or by laboratory manipulation, from a different molecule or from another part of the same molecule, resulting in a new genetic combination.
A form of DNA produced by combining genetic material from two different sources by means of genetic engineering. Recombinant DNA can be used to change the genetic makeup of a cell, as in adding a gene to make a bacterial cell produce insulin.
a DNA molecule in which the genetic material has been artificially broken down so that genes from another organism can be intro-duced and the molecule then recombined, the result being alterations in the genetic characteristics of the original molecule.See also: Heredity
