Exogenous DNA refers to DNA that comes from an external source, rather than being produced by the organism itself. Some synonyms for exogenous DNA include foreign DNA, external DNA, non-native DNA, and introduced DNA. These terms all refer to DNA that has been introduced into an organism from a different source, such as from a virus, bacteria, or another organism. Exogenous DNA can have diverse applications in scientific research, genetic engineering, and biotechnology, such as in the production of genetically modified crops or gene therapy for genetic disorders. Understanding the various synonyms for exogenous DNA can help scientists, researchers, and students communicate more effectively in their work.
