2 RNA structure RNA can be described according to the primary sequence (A), a secondary structure (B) which may contain various structural elements, a super-secondary structure (C) which may contain pseudoknots another tertiary interactions, and a three-dimensional structure (D) wich may interact with proteins (green).

3 in vivo RNA structure is often predicted by computer algorithms In silico These algorithms can be modified to include restraints or constraints on the structure (places where you know are unpaired or base-paired) Often different structures are predicted if restraints are included (bottom) or excluded (top) In vivo Bevilacqua, P.
