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.
nuclear DNA (nDNA) the DNA of the chromosomes found in the nucleus of a eukaryotic cell. recombinant DNA DNA artificially constructed by insertion of foreign DNA into the DNA of an appropriate organism so that the foreign DNA is replicated along with the host DNA.NA. complementary DNA (cDNA), copy DNA DNA transcribed from a specific RNA through the action of the enzyme reverse transcriptase. mitochondrial DNA (mtDNA) the DNA of the mitochondrial chromosome, existing in several thousand copies per cell and inherited exclusively from the mother.
