Genetic engineering, also called gene editing or genetic modification, is the process of altering an organism's DNA in order to change a trait. This can mean changing a single base pair, adding or deleting a single gene, or changing an even larger strand of DNA. Using genetic engineering, genes from one organism can be added to the genome of a completely different species. It is even possible to experiment with synthesizing and inserting novel genes in the hopes of creating new traits.
Many products and therapies have already been developed using genetic engineering. For example, crops with higher nutritional value, improved taste, or resistance to pests have been engineered by adding genes from one plant species into another. Similarly, expression of a human gene in yeast and bacteria allows pharmaceutical companies to produce insulin to treat diabetic patients. In 2020, scientists had their first successful human trial with CRISPR (a genetic engineering technique), to correct a mutant gene that causes sickle cell anemia, a painful and sometimes deadly blood disease.
There are many different genetic engineering techniques, including molecular cloning and CRISPR, and new techniques are being developed rapidly. Despite this variety, all genetic engineering projects involve carrying out four main steps:
- Identifying the trait to be introduced, eliminated, or otherwise modified.
- Determining what piece of DNA needs to be added or removed in order to get the desired trait modification.
- Making the physical modifications to the organism's DNA.
- Verifying that the trait has been modified as desired.

Have you ever wondered how scientists get a sample of DNA from a plant, animal, or other organism? All living organisms have DNA. DNA, which is short for deoxyribonucleic acid, is the blueprint for almost everything that happens inside the cells of an organism — overall, it tells the organism how to develop and function. DNA is so important that it can be found in nearly every cell of a living organism. In this activity, you will make your own DNA extraction kit from household…

Did you know that you can change the genetic code of an organism? This technology is called gene editing or genetic engineering. Using gene editing tools, researchers can delete or modify existing genes in an organism, or even add new ones! With this ability, they can alter the way an organism—such as a bacteria, a plant, or an animal—looks or functions. For example, crops can be modified to become more drought-resistant, or bacteria can be engineered to produce medicine such as…
