Cloning Presentation Cloning Presentation Presentation Transcript

  • What is Cloning? Cloning should not be banned.
  • 1- DNA cloning/ Gene cloning 2- Reproductive cloning (Dolly) 3- Therapeutic Cloning 3 types of cloning:
    • 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
  • 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
  • “ 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
  • 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
  • Works Cited
