The right answer is Transgenic organisms can produce a desired product that may benefit other organisms.
A transgenic organism contains DNA combining stably integrated in all its cells. In other words, the organism, be it a plant, an animal or a microorganism, has a new piece of DNA embedded in it. a chromosome in each of its cells. This “new piece” of DNA usually contains a gene from another organism (plant, animal or other) that has been modified to be expressed in the new organization. A transgenic organism may even possess the DNA of another organism of the same species. The inserted gene can be called the transgene.
Currently, diabetics are treated by injecting insulin from either a healthy human donor or cultures of genetically modified (transgenic) bacteria that secrete the protein.
