What are GMOs and how are they made? In this video, we explain genetically modified organisms in simple words — from how humans have been modifying crops for 10,000 years through artificial selection, to modern genetic engineering with Agrobacterium, Ti plasmids, and gene guns. Learn the step-by-step process of creating Bt corn, the difference between cisgenics and transgenics, and what the real GMO safety debate is about.
Whether you're a biology student, curious about the food you eat, or want to understand the science behind the GMO debate, this beginner-friendly animated explainer covers both the science and the controversy.
