A GMO, short for Genetically Modified Organism, refers to any plant, animal, or microorganism that has been altered through biotechnology. This means their genetic makeup has been changed in a lab, rather than through traditional breeding methods. These modifications can also be present in the ingredients derived from GMOs, which are commonly found in food and various personal care products.
GMO developers employ biotechnology to intentionally change the fundamental characteristics of an organism. Biotechnology encompasses a range of techniques, including the use of synthetic gene sequences to modify an organism’s genetic material, such as DNA or RNA. It can also involve forcing the combination of genes from vastly different species that would not naturally interbreed. When these biotechnological methods are applied to a living organism, the resulting product is classified as a GMO. While GMOs find applications across numerous industries, the primary focus concerning GMOs often revolves around their presence in our food, personal care items, and animal feed.
Some common examples of GMOs include crops engineered for pest resistance or herbicide tolerance, and even certain animals modified for faster growth or disease resistance.

The Building Blocks of Life: Understanding DNA
Every living organism on Earth is built from cells. Within these cells lies genetic material, which dictates the organism’s traits and functions. This genetic material, known as DNA, essentially contains the “building blocks of life.” It influences everything from an organism’s appearance and growth to its lifespan.
DNA resides within the delicate and complex structure of cells, protected from external elements that could cause damage and harm the organism. Due to these natural protective mechanisms, altering genetic material without causing harm is a complex task. However, GMO developers utilize biotechnology techniques to overcome these cellular defenses without destroying the organism itself. Biotechnology enables the creation of novel gene sequences that may never have occurred in nature, leading to organisms that are entirely new to the human diet and environment.

GMOs: A Departure from Traditional Breeding
Humans have been involved in agriculture for over 12,000 years, selectively breeding plants and animals to enhance desired traits. Traditional breeding techniques rely on natural reproduction processes like cross-pollination, along with some modern lab techniques such as cell culturing and chemical mutagenesis.
However, these traditional methods are fundamentally different from biotechnology. Biotechnology, in the context of GMOs, is a relatively recent innovation, emerging in the 1970s. GMO developers leverage biotechnology to directly manipulate an organism’s DNA or RNA, or to bypass natural reproductive barriers. This leads to the creation of a diverse array of GMOs. These include crops with modified DNA to produce their own insecticides, resist herbicides, or enhance their nutritional value. Biotechnology can even be applied to animals to alter growth rates and physical characteristics, or even to limit their reproductive capabilities.
