WebA tRNA contains hairpins as well, though the hairpins play different roles in the two cases. In transcription termination, the hairpin causes the RNA polymerase to stall and the transcript to separate from the DNA. In a tRNA, multiple hairpins form and give the tRNA molecule the 3D shape it needs to perform its job of delivering amino acids.
