What are GMOs?
GMOs, or genetically modified organisms, are living organisms that have been altered through bioengineering. This scientific process involves modifying the genes of an organism, such as plants, animals, or bacteria, to achieve specific desired traits. In the case of GMO crops, scientists identify genes that contribute to certain traits, make copies of those genes, and insert them into the DNA of another plant’s cells. This genetic modification allows the plant to possess characteristics that it wouldn’t otherwise have, such as resistance to pests or increased nutrient content.
The use of GMOs in agriculture is widespread, especially in the United States. Genetically modified seeds, such as those for corn and soybeans, are commonly used in farming practices. These modified crops have been developed to improve food production, increase plant resilience, and provide other agricultural benefits. The genetic modification process allows for more precise and efficient changes to an organism’s genetic makeup, compared to traditional plant breeding methods.
