tRNA molecule. This plays an important role in protein synthesis. This is the smallest RNA seen in the cytoplasm of the cell. This acts as the adapter molecule during protein synthesis. Each tRNA has a triplet code which is complementary to a codon in mRNA called anticodon. It also has an amino acid acceptor end which binds amino acids. The secondary structure of tRNA looks like clover leaf.
