What actually is cloning?

The cloning used in society our days is also known as reproductive cloning, meaning that a genetic twin is created of another organism. DNA is transferred and extracted from the donor and inserted into the egg of another organism of the same species (1). The nucleus is removed from the egg cell meaning that the it will duplicate the DNA of the donor cell (2).

Steps(3):
1. Isolate the donor cells
2. Remove the nucleus from the egg cells and discard
3. Transfer the somatic cell nucleus from the donor into the egg cell without the nucleus
4. Stimulate cell division
5. Implant embryo in the surrogate mother
6. Deliver the baby
