Cloning Humans Scott Stewart Definition and types Cloning is the production of 1 or more individual plants or animals (whole or in part) that are genetically identical to an original plant or animal. I’ll discuss two types: (1) Reproductive cloning (aka adult DNA cloning) (2) Therapeutic cloning (aka biomedical cloning) Reproductive cloning Produces a duplicate of an existing animal Dolly and the Raelians DNA from an ovum removed and replaced with the DNA from a cell removed from an adult animal The fertilized ovum (called a pre-embryo) implanted in a womb and allowed to develop into a new animal Very controversial: banned in many countries Reproductive cloning Therapeutic cloning Initial stages identical to reproductive cloning However, stem cells are removed from from the pre-embryo to produce tissue for a whole organ for transplant back into the person who supplied the DNA Therapeutic Cloning 2 Totipotent and Pluripotent stem cells Somatic Cell Nuclear Transfer Goals: Produce healthy organs, drug testing, experiments Controversy Some concerns are held for all forms of cloning, others are specific to one form or the other
