Abstract
тmRNA is a small RNA molecule, found only in bacteria, that exhibits properties of tRNA and mRNA. TmRNA involved in process of «trans-translation» when protein translates from two different RNA molecules and one of them is tmRNA. Its function is decreasing of translation error amount by releasing of stalled ribosomes and degradation of incorrect proteins.
