Genetic Engineering Gizmo Assessment Quiz with
complete solution
1. The corn plants in the image below have been grown with Lepidoptera sp. larvae,
insects that feed on the corn's cob and leaves. Select the statement that is correct,
based on the image.
B. A resistance gene was inserted into the plant on the right that makes the corn
resistant to Lepidoptera sp. larvae.
2. In the image below, the corn plant on the left has been grown with Lepidoptera sp.
larvae, insects that feed on the corn's cob and leaves. The corn plant on the right was
not exposed to insects. Does this experiment provide enough information to conclude
that the plant on the right is resistant to Lepidoptera, and why?
C. No, we cannot conclude whether or not the corn plant on the right is resistant
because it has not been exposed to Lepidoptera.
3. A new pest is found that only feeds on corn plant leaves. Livestock eat corn cobs.
Which promoter would you choose if the modified gene produces toxins that are not
safe for livestock to ingest?
B. Promoter 2.
4. Coleoptera larvae, insects that eat corn plant roots, are shown in the petri dishes
below. Select the statement that is correct assuming that the following choices were
made as represented by the image below.
D. The plant will be sensitive and mutated.
5. The white disks in the petri plates are soaked in herbicide, which affects the roots,
stalks, leaves, and cobs of a corn plant. If the transformed plants were grown in the
presence of herbicide, which corn plant would result from the choices shown below?
C. Corn plant C.
