Figure 5From: RNA FRABASE 2.0: an advanced web-accessible database with the capacity to search the three-dimensional fragments within RNA structuresExample of the use of the wildcard characters "^" and "$" in the query. The figure shows two example structures: (a) RNA duplex and (b) tRNA acceptor stem. The input pattern used to run search algorithm and the number of matching fragments are provided for each example. Residues, base pairs and strands are marked by employing the same convention as that used in Figure 4.Back to article page
