Answer:
miRNAs are short sequences of RNA (20-24pb) with high self-complementarity, allowing it to fold over itself (hair fork structure). This makes miRNA super stable, even in the highly reactive atmosphere of the cytoplasm.
miRNAs do not have RBPs as in RNAm.  They are linked with different proteins of the post-transducer machenary, such as argonaute, DICER or others, to serve as a guide to the adequate protein complex. 
 
        
             
        
        
        
False.
Artries in general have thicker walls than veins. (thicker tunica media)
This is because artries need to withstand high blood pressure when the heart pumps the oxygenated blood to the rest of the body while veins carry blood (deoxygenated) at lower pressures, hence they are thinner compared to artries
