Summary Introduction

To explain: The response against genetically modified food critics.

Concept introduction: Genetically modified foods have been made by scientist by introducing certain changes in the DNA or genome of crop plants by using genetic engineering. It is very different from breeding because in this instead of getting random genes, scientists put a desired gene directly into the plant’s DNA.

Much of the controversy over genetically engineered foods has centered on whether special labeling should be required on all products made from genetically modified crops. Some people have advocated labeling that identifies the product as having been made from genetically modified plants. Others have argued that food labeling should be required to identify only the ingredients, not the process by which they were produced. Choose a side in this issue and justify your stand.
Genetically modified organisms (GMOs) are used to create human growth hormone, insulin and clotting factor proteins that are used to treat dwarfism, diabetes and hemophilia respectively. Several crops such as corn and soybean have also been genetically modified in order to facilitate either the management or growth of these crops. Why do you think there is push back or opposition against the use of GM food crops but not in the use of products such as insulin, which is also created using GMOs?
Examples of GMOs Correctly classify examples of bacteria, plants, and animals that have been genetically modified. Produce biofuels and other chemicals for use in manufacturing Genetically Modified Bacteria Reduce the impact of pest species by either deterring them or killing them Modified to have increased nutritional value by reducing their susceptibility to disease, increasing their rate of growth, and improving the quality of the meat/milk Provide organs for humans for transplantation Serve as models for studying human diseases such as cystic fibrosis Produce enzymes to enhance metabolic pathways to aid in the breakdown of toxic chemicals in the environment Allow organisms to better face environmental challenges such as drought, heat, and high salt content in the water supplies Reduce the number of pest species that are vectors for diseases such as Zika and dengue fever Modified to produce antibodies, vaccines, and enzymes that can be used in the treatment of humans Provide plant's…
