Cloning is defined as the process of generating copy of a cell, part of body, or a complete organism, which is genetically identical to the parent organism. It is a natural phenomenon seen in asexual reproduction. In artificial biological processes, the generation of an identical copy of desired cell or organism, which in nature show variations due to sexual reproduction, is called cloning. The process is generally used to produce cell or cell products with desirable traits. In molecular biology, the process of cloning is used to replicate DNA and RNA. The first successfully cloned animal was a sheep named Dolly.
