Transcript

  • 1. Genetically Modified Food By Jenna Pauly
  • 2. What are GM Foods? Genetically modified foods, or GM foods: Foods that have been modified by scientist and its genes have been changed or a new gene was injected into it.Example: A banana would not be the way it is today without genetic modification. They would have seeds and oddly shaped. Not Modified Genetically Modified
  • 3. Why GM Foods?We genetically modify food to: Protect against pests or pesticide Add nutrients that it may lack Help it thrive in different or harsher environments Protect it from diseaseThe banana is genetically modified to resist a bacterium called Xanthomonasmusacearum( BXW) and given extra nutrients to help as a food source in places such as Uganda and East Africa.http://www.abc.net.au/catalyst/stories/2544893.htm Video about GM bananas
  • 4. Types of GM FoodsBesides the Banana, other foods such as: Tomatoes Corn Soy beansAnd othersAre also genetically modified. Most of the foods we consume are genetically modified. About 60% of processed foods contain genetically modified ingredients. How do they come to be modified?
  • 5. GM ProcessThe Process for GM has 8 steps and begins with:1. Isolation of the gene(s) of interest- A chromosome is used to identifythe gene(s) responsible for the desired trait in the organism. Example:the Xanthomonasmusacearum2. Insertion of the gene(s) into a transfer vector- The desired trait is putinto the plasmid.3. Plant transformation-The plasmid contained inside A. tumefacienscells transfers the plasmids and new gene into the plants chromosomes.

  • 7. Cons of GM FoodAlthough GM foods may seem like a great idea to some people, to others they feel its wrong. Might cause other species to have unknown diseases Insects could become nonresistant to the natural pesticides Fear that the transfer of genes between two unrelated species can transfer allergens making people sick Some people believe GM is messing with nature and its wrong to mess with it
  • 8. The End
