Cloning 8 b

  1. 1. Cloning What Is A Clone? What Is Cloning? What is The Main Process? What Is good or not So Good about Cloning?
  2. 2. Clones are organisms that are exact genetic copies. Every single bit of their DNA is identical. So…What is a clone?
  3. 3. Which process involve natural “Clones”?
  4. 4. What is cloning? The term cloning describes a number of different processes that can be used to produce genetically identical copies of a biological entity. The copied material, which has the same genetic makeup as the original, is referred to as a clone. Researchers have cloned a wide range of biological materials, including genes, cells, tissues and even entire organisms, such as a sheep.
  5. 5. How was dolly made?
  6. 6. There are three different types of artificial cloning: gene cloning, reproductive cloning and therapeutic cloning. • Gene cloning produces copies of genes or segments of DNA. • Reproductive cloning produces copies of whole animals (Somatic Cell Nuclear Transfer, The Roslin Technique, The Honolulu Technique). • Therapeutic cloning produces embryonic stem cells for experiments aimed at creating tissues to replace injured or diseased tissues (Induced pluripotent stem cell).
  7. 7. What is cloned DNA used for? • Work out the function of the gene • Investigate a gene’s characteristics (size, expression, tissue distribution) • Look at how mutations may affect a gene’s function • Make large concentrations of the protein coded for by the gene What is Reproductive cloning and Therapeutic Cloning used for? • Cloning animal models of disease • Making stem cells • Copies of animals with desirable traits • Bringing back endangered/ Extinct species Would You Clone your Dog?
  8. 8. So What Is The Problem With Cloning? Moral, Ethical Dilemmas Shorter Life Spams High Risk, Low Success. Are you for Cloning? Are you Against Cloning? Are you Neutral about It?
