Following statements are regarding to the drosophila.

 A. At the completion of oogenesis, the bicoid message is anchored at the anterior end of the oocyte and the nanos message is tethered to the posterior end in translationally dormant condition.

 B. The translation inhibitors Smaug and CUP. Smaug binds to the 3’UTR of both bicoid and nanos mRNA and recruits the CUP protein that prevents the association of the message with the ribosome as well as recruiting other proteins that deadenylate the message and target it for degradation.

 C. The bicoid-Exuperantia complex is transported out of the nurse cells and into the oocyte via microtubules (Kinesin ATPase).

 D. Two other maternally provided mRNAs—caudal and hunchback are critical for patterning the anterior and posterior regions of the body plan, respectively.
