  • Human cloning

    1. 1. Geneticists groupCloning
    2. 2. WHAT EXACTLY IS CLONING? Cloning is the creation of an organism that is an exact geneticcopy of another. This means that every single bit of DNA is the same between the two!
    3. 3. The types of cloningHybrid cloning Therapeutic cloning Reproductive cloning
    4. 4. HOW IS CLONING DONE? How does one go about making an exact genetic copy of an organism? There are acouple of ways to do this: artificial embryo twinning and somatic cell nuclear transfer. How do these processes differ?
    5. 5. Artificial Embryo Twinning Artificial embryo twinning is the relatively low-tech version of cloning. As the name suggests, this technology mimics the natural process of creating identical twins. Artificial Process Video
    6. 6. Somatic Cell Nuclear Transfer Somatic cell nuclear transfer, (SCNT) uses a different approach than artificial embryo twinning, but it produces the same result: an exact clone, or genetic copy, of an individual. This was the method used to create Dolly the Sheep. Somatic Process Video
    7. 7. AdVantages andDisadvantages
    8. 8. History of cloning inmammalsDolly the sheep Herd of mice Cat (CC)
    9. 9. DEGREE OF AGINGOne risk of cloning is that the cells of the clone can aging faster than the normal persons
    10. 10. IMPORTANCE OF RESEARCH INTO CLONINGIt is important that we continue to investigate this area to improve the technique and reduce the risks
    11. 11. No current clinical treatments Few successes in animal modelsDifficulty in obtaining pure cultures in the dishQuestions regarding functional differentiation Difficult to establish and maintain Current and Problem of immune rejection potential Potential for tumor formation and tissue embryonic destruction stem cell Genomic instability problems: Ethically contentious
    12. 12. Current CancersClinical Usesof Adult leukemiasStem Cells Autoimmune diseases Anemias Bone deformities Stroke Parkinson’s Skin
    13. 13. This is a very relevant question.There is indeed a relationship between the clone and originalone. Since we are not facing a real situation, it is not urgent to create a new concept that would fit this "relationship".

    17. 17. Reproductive Cloning|Adult dna cloning Reproductive cloning is a technology used to generate an animal that has the same nuclear DNA as another currently or previously existing animal. Human cloning also falls into this category. e.g. identical twins
    18. 18. Therapeutic Cloning The purpose of therapeutic cloning is to extract the stem cells from the embryos. Stem cells can be used to treat heart disease, Alzheimers, cancer, and various other diseases. e.g. heart or even just a few cells
    19. 19. Hybrid cloning A clone has been made ​from this technique. It was achieved using a cell from a mans leg and a cows egg. It is called hybrid because it uses 2 different power sources.
    20. 20. Advantages 1/Potential benefits to modern medicine 2/Helping infertile couples 3/Reverse the aging process 4/Protecting Endangered Species 5/ Improving food supply
    21. 21. Disadvantages 1/The Element of Uncertainty 2/Inheriting diseases 3/The Potential for Abuse
    22. 22. Dolly the sheep She was born on 5 july 1996. She was cloned by Ian Wilmut and keith campbell in Scotland Was the first mammal to be cloned Died from a progressive lung disease
    23. 23. Herd of mice The first cloned mammals was a mouse (named "Masha") in 1986, in the Soviet Union. The cloning was done from an embryo cell. The first mouse from adult cells, Cumulin, was born in 1997 at the University of Hawaii at Mānoa. Over a dozen clones as of 2002.
    24. 24. Cat (CC) Was born in December 2001, scientists at Texas A&M University created the first cloned cat, CC (CopyCat).
