recombinant DNA
recombinant DNAn. 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.recombinant DNA n (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 recombinant DNA
n. 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. [1970–75] re·com·bi·nant DNA (rē-kŏm′bə-nənt) 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.recombinant DNAa 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: HeredityThesaurus| Noun | 1. | recombinant DNA - genetically engineered DNA made by recombining fragments of DNA from different organismsrecombinant deoxyribonucleic aciddeoxyribonucleic acid, desoxyribonucleic acid, DNA - (biochemistry) a long linear polymer found in the nucleus of a cell and formed from nucleotides and shaped like a double helix; associated with the transmission of genetic information; "DNA is the king of molecules" |

recombinant DNA
recombinant DNA[‚rē¦käm·bə·nənt ¦dē¦en′ā] (cell and molecular biology) Deoxyribonucleic acid (DNA) that has been altered (caused to recombine) by rearrangement of its sequence, addition or deletion of DNA segments, or introduction of foreign DNA segments (for example, a gene from another organism introduced into an organism's genome). recombinant DNA
re·com·bi·nant DNAaltered DNA resulting from the insertion into the chain, by chemical, enzymatic, or biologic means, of a sequence (a whole or partial chain of DNA) not originally (biologically) present in that chain.recombinant DNAn. 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.recombinant DNA DNA produced by the artificial linkage, in the laboratory or factory, of DNA from different sources. See also GENETIC ENGINEERING.recombinant DNA - DNA produced by joining together DNA sequences from different sources in vitro; often this involves VECTOR (2) DNA and foreign DNA to form a recombinant vector for use in GENETIC ENGINEERING.
- DNA produced by natural RECOMBINATION in vivo.
