Education of GMOsCurrent LectureClass Discussion GMOs as food They put genes in GMOs that code for proteins and then express themselves Herbicide resistant plants allow farmers to spray herbicides on the plants to kill weeds without harming the plantsVitamin A rice, we have introduced a gene that allows rice to produce beta carotene to help enhance the nutritional value of rice which would benefit countries around the world.BT corn is a gene that produces a toxin that kills bugs Ringspot virus resistant, it allows the plant to be resistant to ringspot What effect might GMOs have on our health?- they haven’t caused harm to a single person or animal- GE traits are composed of the same chemical building blocks that we eat everyday- Within one hour 98% of the DNA in foods is digested completely and most proteins breakdown soonerIs the process of adding genes to our food by genetic engineering any more risky than adding genes by conventional breeding?Genetic engineering and conventional breeding pose similar consequencesHow might a gene inserted into a plant affect its nutritionIrradiated Rice – a natural induced genetic change?We induce mutations to wild type rice which creates new alleles and then select for those new traits they think are beneficialWhy shouldn’t we label GMOsIt scares a lot of customers even though theres no evidence that theyre harmful Can GMOs can cause allergies?GMOS have not caused an allergic reaction in humansThere has been a case in which a adverse reaction as documented in the lab priorto commercialization, this was never released to the
