Arabidopsis contains five genes encoding phytochromes, PHYA–PHYE, four of the five phytochromes appear mostly light-stable in the plant and function primarily in the regulation of LFRs and of shade avoidance involving changes in the R:FR ratio.

The regulative ability of the limb bud has recently been highlighted by a remarkable experiment of nature. In numerous ponds in the United States, multilegged frogs and salamanders have been found. The presence of these extra appendages has been linked to the infestation of the larval abdomen by parasitic trematode worms. The eggs of these worms apparently split the developing tadpole limb buds in several places, and the limb bud fragments develop as multiple limbs. This shows:

A. The limb field represents a harmonious equipotent system. 

B. The limb field do not represents harmonious equipotential system because different types of genes express during proximal to distal growth.

C. The limb field represents coupled system wherein one gene maintain the expression of other genes.

D. The limb field represents a harmonious equipotent system because only Hox genes expresses all along the limb axis.

E. The limb field represents cells of the limb region can be instructed to form any part of the limb.

You have identified a transcription factor and hypothesize that it binds to the promoter region of a gene that encodes a protein that causes cells to stop dividing. In order to test the interaction between the transcription factor and the DNA you will need to do a specific assay. Which one of the following would you use to test your hypothesis?
