The background of cloning and human cloning
What is cloning?
Somatic cell nuclear transfer (SCNT)
Induced pluripotent stem cells (iPSCs)
Reproductive cloning
Making an entire cloned human, instead of just specific cells or tissues The possibility of reproductive cloning of human has raised controversies
• The process of producing similar populations in nature
• The processes used to create copies in biotechnology Molecular cloning Cell cloning Organism cloning
A famous example of organism cloning-
Dolly the sheep
What is human cloning?
The creation of a genetically identical copy of a human.
Therapeutic cloning Reproductive cloning
Therapeutic cloning
Cloning cells from a human for use in medicine and transplants It is not in medical practice anywhere in the world How to do it? Somatic cell nuclear transfer (SCNT) Induced pluripotent stem cells (iPSCs)
Use it properly !
Cons of human cloning
Reproductive human cloning Are they humans? No Discrimination Enslavement Extermination Yes
Expensiveness
Better characteristics
