Final answer:
Gene therapy can introduce cloned genes into a host species, allowing for the production of desired traits. Recombinant DNA technology and transfection are used in this process.
Step-by-step explanation:
Gene therapy can introduce cloned genes into a host species. This is done by using recombinant DNA technology and transfection. Transgenic organisms, such as transgenic plants, are created using molecular cloning techniques.
Transgenic organisms possess DNA from a different species, usually generated by molecular cloning techniques, and can be used to produce desired traits.
For example, genetically engineered plants, called transgenic plants, are used for agricultural and pharmaceutical purposes.
