The short answer is no, neither MSG or animal extraction are from GMOs, nor is MSG, animal extraction, or animal products/animal DNA in GMOs.
When people refer to Genetically Modified Organisms (GMOs), they are referring to precision plant breeding using genetic engineering (also called GE). It allows plant breeders to take a desirable trait (like resistance to drought, insects, weeds, and disease) from one plant or organism and transfer it to the plant they want to improve, as well as make a change to an existing trait in a plant they are developing. You may have also heard of agricultural biotechnology or biotech seeds. These are terms that may be used to refer to the same thing – a genetically modified organism (GMO).
GMOs are created to achieve a desired trait, such as resistance to an insect or improvement to the ripening process, in order to better meet a customer’s needs.
Posted below is a five minute video that offers a great visual illustration on how GMOs are made:
