Which statement describes the process of creating a transgenic organism?

• A. Insertion of recombinant DNA from a different species into the host genome
• B. Cloning
• C. Natural selection
• D. Mutation breeding

Answer: (A)

Introducing foreign DNA from a different species into an organism's genome to create a transgenic organism is what defines this process. Through recombinant DNA technology, a gene of interest is combined with DNA that can integrate into the host genome and be expressed, so the organism carries and passes on the foreign gene to its offspring. Cloning, by contrast, is making a genetically identical copy of an organism or gene rather than adding new genes from another species. Natural selection describes how traits become more common over generations due to differential survival, not how new genes are introduced. Mutation breeding involves inducing mutations to generate variation, not transferring genes across species. So the description fits the insertion of recombinant DNA from a different species into the host genome.
