Storyboard Description

An issue about the genetic modification.

Storyboard Text

  • Hello, I'm a genetically modified fish. Genetic modification is a powerful method of introducing desirable traits into plants and animals by using recombinant DNA technology.
  • When a scientist genetically modifies a plant, they insert a foreign gene in the plants own genes the result is that the plant receives the characteristics that are in the genetic code.
  • To do this first the scientist maps the gene. Second, the scientist makes several copies of the gene. Next, the scientist transfers the desired gene to the plants own genes. There are three ways of inserting the genes; using a "gene cannon" , a soil bacteria, or a material called protoplast.
  • Ethical issues begin to appear with genetic modification, including concerns for animal welfare, can arise at all stages in the generation and lifespan of an individual genetically engineered animal.
  • Genetically modified organisms will have a big affect on the environment because they will out compete the other native species in that area. These new species could cause overpopulation due to no predatation and a big foodsource for them.
  • As animal health professionals, veterinarians can also make important contributions to policy discussions related to the oversight of genetic engineering as it is applied to animals, and to regulatory proceedings for the commercial use of genetically engineered animals.
