strigolactone biosynthesis takes place , find the correct sequence of these signal transduction pathways;

a) D14* hydrolyses strigolactone and releases the products of hydrolysis. 

b) D14 disengages from the SCFMAX2 complex and returns to its original conformation, allowing it to respond to fresh strigolactone signal.

c) D14* interacts with the F-box protein MAX2 and the other partners of the SCFMAX2 ubiquitin ligase complex.

d) The α-/β-fold hydrolase D14 binds and reacts with strigolactone, changing its conformation to the active form, D14*

e) Target protein(s) are recognized by the D14*–SCFMAX2 complex and are ubiquitinated

When Lucifer yellow, a small dye, is injected into a neuron of the retina, neighboring neurons become rapidly labeled. If the retina is incubated in dopamine prior to Lucifer yellow injection, only the injected neuron becomes labeled. These findings suggest which of the following?

I. Neurons of the retina communicate via gap junctions.

II. Dopamine is transferred between cells via gap junctions.

III. Dopamine decreases the permeability of gap junctions.
