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
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
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?
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.
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
