One of the possible concerns about genetically modified foods is that they might kill organisms that we don't want to kill. Which of the following is an example of this phenomenon?
a) Featherless chickens have become prey to more animals than feathered chickens.
b) Genetically modified super-sized salmon have been known to kill the bald eagles that generally feed on them.
c) The pollen from plants containing insect-killing Bt genes can be blown onto other plants. Insects that we don't want to kill, such as monarch butterflies, may be killed by such pollen.
d) Bears eating genetically modified corn may be poisoned by the Bt gene introduced to the corn to act as a pesticide.
e) In the Irish Potato Famine, more than one million people died as a result of the lack of genetic diversity in the potato crop.
Ans: c) The pollen from plants containing insect-killing Bt genes can be blown onto other plants. Insects that we don't want to kill, such as monarch butterflies, may be killed by such pollen.

Why is the formation of a BCR-ABL fusion gene a carcinogenic event?
A. The tyrosine kinase activity of the ABL gene becomes inactive. B. The tyrosine kinase activity of the ABL gene is now controlled by a weak promoter resulting in less tyrosine kinase activity. C. The tyrosine kinase activity of the ABL gene becomes unregulated leading to uncontrollable cell division. D. The tyrosine kinase activity of the ABL gene is reduced due to truncation of the protein product. E. The tyrosine kinase activity of the BCR gene is increased in the fusion protein product.
