Which statement describes which organism has been genetically engineered?
The potato plant, because the transferred gene was added to its cells.
Both the bacterium and the potato plant, because the gene passed between them.
The bacterium, because it was the source of the transferred gene.
The insect pest, because the transferred gene makes the plants resist it.
