There are three main types of cloning: 1) DNA cloning which clones genes for uses like protein production and vaccine development, 2) reproductive cloning which produces genetically identical animals but risks are high inefficiency and potential harm, and 3) therapeutic cloning which produces stem cells for research on treating diseases but risks include killing embryos.

1. What is Cloning? Cloning should not be banned.

2. 1- DNA cloning/ Gene cloning 2- Reproductive cloning (Dolly) 3- Therapeutic Cloning 3 types of cloning:

3. Practiced since 1970 Common practice in molecular biology labs today. Clones Genes; not cells or entire animals. For large protein production Study of viruses Vaccines No controversies in this branch of cloning DNA/ Gene Cloning

4. Generate a “twin animal”: same DNA (Dolly) Benefits: 1) Maintain good DNA in animal reproduction. 2) Cloning genetically modified animals: - Xenotransplantation (avoid tissue rejection) - Insulin producers Risks: 1) Highly inefficient: - Die mysteriously - High costs. 2) Morally wrong to experiment with animals. 3) Could lead to the cloning of humans. Reproductive Cloning

5. “ Production of human embryos for use in research: Stem cell research” Possible Benefits: Produce whole organs from cloned stem cells. Produce healthy cells for transplantation. Reduce need for organ donors Test drugs, understand diseases. Risks: Killing embryos in the process. Therapeutic Cloning

6. Cloned animals: (Reproductive Cloning) First cloned rabbit by Chinese scientists First cloned horse by Italian Scientists Snuppy: first cloned dog from South Korea. CC “CopyCat” First cloned cat from Texas. Ralph: The first cloned rat by French scientists
