What is atransgenic organism? ~ a transgenic, or genetically modified, organism is one that has been altered through recombinant DNA technology, which involves either the combining of DNA from different genomes or the insertion of foreign DNA into a genome GloFish http://en.wikipedia.org/wiki/File:GloFish.jpg
- 3. How transgenic organisms work… ThreeMain Methods… DNA Microinjection A foreign gene is directly injected into a fertilized egg that is put into a female animal that acts as a surrogate mother for the egg. Retrovirus-Mediated Gene Transfer A retrovirus is a virus that attaches to an organism’s DNA and changes it to include a new characteristic. Scientists expose ordinary cells to a retrovirus when they are trying to create transgenic animals. Embryonic Stem Cell-Mediated Gene Transfer Stem cells are blank cells that can turn into any type of cell. Scientists modify these cells, and then add them to an embryo, which is a fertilized egg that develops and grows until it hatches or is born.
