Scientists have taken genes from a species of bacteria that is pathogenic to several insects and inserted the genes into potato plants. The bacterial genes cause a cell to produce toxins that kill the insects. As the potato plants grow, every cell of the plant contains the toxin-producing genes. This makes the potato resistant to attack by crop pests. Which of the following is a limitation of this new technology?
A.
There are no foreseen limitations with inserting bacterial genes into crop plants.
B.
The introduced gene will cause more diversity in the potato's genome, thus causing the potato plant to become extinct.
C.
The genetically altered potato plants will kill off so many insects that companies that manufacture pesticides will soon go out of business.
D.
Over time, insects are likely to develop resistance to the bacterial toxin.
