GMOs, or “Genetically Modified Organisms,” are plants or animals created through the gene splicing techniques of biotechnology (also called genetic engineering, or GE). Genetically modified plants and animals have had their DNA irrevocably changed in a way that can’t be replicated in nature.
One of the most widely used GMO plants is the soybean. These beans have an herbicide resistant gene from bacteria inserted into their DNA. Such a trans-species, even trans-kingdom, DNA mutation is impossible in the natural world because bacteria would never be able to breed with a soybean plant.
