DNA cloning is the process of making multiple, identical copies of a particular piece of DNA. In a typical DNA cloning procedure, the gene or other DNA fragment of interest (perhaps a gene for a medically important human protein) is first inserted into a circular piece of DNA called a plasmid.
Cloning Vectors: A cloning vector is simply a DNA molecule that can be inserted into a host cell and replicates inside the host (bacteria or yeast), producing many copies of itself and the insert DNA.All cloning vectors contain -.ll cloning vectors contain 1  -. A sequence that allows for the propagation of itself in the host. 2  An insertion site for the foreign DNA-also called a multiple cloning site that can be cut by several restriction enzymes. 3  A method for selection of the host cells that contain the insert DNA of interest.
