Gene cloning or "molecular cloning" are a set of experimental methods used in molecular biology that are used to assemble DNA molecules and achieve their copying within recipient organisms. The use of the word cloning refers to the fact that the method comprises the copied from a single molecule of DNA starting with a single living cell to produce a large population of cells that contain identical DNA molecules. Molecular cloning usually uses DNA sequences from two different organisms: the species that is the source of the DNA that you want to clone, and the species that will serve as the live receptor for copying the recombined DNA.
