Definition of cloning

There are three types of cloning. First, is known as recombinant DNA technology or DNA cloning. It is the process or transferring the DNA fragment from one organism to another organism or is better known as self-replicating genetic element. Second is call reproductive cloning. It is a technology that used to generate an animal that has the same nuclear DNA as another existing animal. Dolly was the example that created by reproductive cloning technology through a process called “somatic cell nuclear transfer” (SCNT). Third type of cloning is therapeutic cloning or also called as “embryo cloning”. It is not to clone human but is used as a production of human embryos in research in order to harvest stem cells that can be uses to study human development and to cure diseases.
