The following questions are based on the drawing of root or stem cross sections shown in Figure 35.2.

Figure 35.2
-While studying the plant Arabidopsis, a botanist finds that an RNA probe produces colored spots in the sepals of the plant. From this information, what information can be inferred?
A)The differently colored plants will attract different pollinating insects.
B)The RNA probe is transported only to certain tissues.
C)The colored regions were caused by mutations that occurred in the sepals.
D)The RNA probe is specific to a gene active in sepals.
E)More research needs to be done on the sepals of Arabidopsis.

Quizplus · Accepted Answer

The fact that the RNA probe produces colored spots specifically in the sepals of the plant suggests that it is specific to a gene that is active in sepals. This inference is supported by the observation that the color is restricted to sepals and not present in other tissues or organs of the plant. Therefore, the correct choice is D.
