  • Title: RNA folding: pseudoknots, loops and bulges.
    Author: Wyatt JR, Puglisi JD, Tinoco I.
    Journal: Bioessays; 1989 Oct; 11(4):100-6. PubMed ID: 2695075.
    Abstract:
    The three-dimensional structures adopted by RNA molecules are crucial to their biological functions. The nucleotides of an RNA molecule interact to form characteristic secondary-structure motifs. Tertiary interactions orient these secondary-structure elements with respect to each other to form the functional RNA. Here we describe the basic structural elements with special emphasis on a novel tertiary motif, the pseudoknot.
