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.
