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.
