Clone (verb)

To "clone" something is to produce copies of it. To clone a piece of DNA, one would insert it into some type of vector (say, a plasmid) and put the resultant construct into a Host (usually a bacterium) so that the plasmid and insert replicate with the Host. An individual bacterium is isolated and grown and the plasmid containing the "cloned" DNA is re-isolated from the bacteria, at which point there will be many millions of copies of the DNA - essentially an unlimited supply. Actually, an investigator wishing to clone some gene or cDNA rarely has that DNA in a purified form, so practically speaking, to "clone" something involves screening a cDNA or genomic library for the desired clone. See also "probe" for a description of how one might start a cloning project, and "screening" for how the probe in used. One can also clone more complex organisms, with considerable difficulty. The much-publicized Scottish research that resulted in the sheep ”Dolly’ exemplifies this approach.
