While studying the plant Arabidopsis, a botanist finds that an RNA probe produces coloured spots in the sepals of the plant. From this information, what can be inferred?
A)The differently coloured plants will attract different pollinating insects.
B)The RNA probe is transported only to certain tissues.
C)The coloured 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.
