Genetic engineering refers to the modification of genetic information in DNA. This allows scientists to make precise changes to genes of living organisms, such as bacteria, plants, and animals. This might be increasing or decreasing the expression levels of a gene, de-activating it completely, or introducing a new gene. Through genetic engineering, scientists can study and unlock biological information. This allows scientists to better understand certain diseases, and potentially leading to the development of new treatments. Genetic engineering also has uses outside of heathcare - for example, addressing agricultural challenges.
