Abstract. A classification of elements of RNA secondary structure is proposed; the classification generalizes the loop classification given by Mathews and Turner. The classification allows one to describe both hpdeudoknot-free, and psedoknotted structures.
Key words: RNA, secondary structure, helix, pseudoknot, loop.
