Transgenic organisms powerpoint

  1. 1. By Stephanie Wilson
  2. 2. What is a transgenic animal?• Transgenic animal: An organism that has had part of another species genome transferred into its own through the techniques of genetic engineering.• Example of a transgenic animal: Mice
  3. 3. How do you create a Transgenic Mouse?•Several methods but one most often used: Transgenic Mouse Process Animation
  4. 4. First Method of Transgenic Mice Creation• (basic steps) Standard Transgenic Approach: 1. Microinject fertilized mouse eggs with transgene
  5. 5. Methods continued…2. Injected eggs are implanted into a fostermother
  6. 6. Methods continued…3. Offspring are then born “Pups”; possiblefounders (have the transgene)
  7. 7. Method Continued…4. Potential founders (pups with the transgene) are found using a PCR analysis and or southern blotting (Black offspring = founders)5. Founders can then be further analyzed for affectsof that transgene
  8. 8. Methods Continue… Transgenic Mice Technology Part 1 Transgenic Mice Technology Part 2
  9. 9. Why create transgenic mice?•Transgenic Mice have: •Aided the study of Alchemies Disease • Aided in study of pancreatic cancer Transgenic Mice aids study of Pancreatic Cancer •Acted as disease models •Tested toxicants •Produced specific proteins helpful in biotechnology
  10. 10. Pros and Cons• Pros – Cheap – Short generation time – Defined genes• Cons – Ethical Concerns • Are the animals treated with respect? – Environmental Issues • What if a genetically modified animal gets loose? – Religious Views • Do we have the right to act as God?
