List of Secondary Structure Databases
If you want to design puzzles based on naturally-occurring RNAs, consider searching for a sequence in one of the online secondary structure databases listed below. You may have to break pseudoknots to create your puzzle. For structures represented in dot-bracket notation, this can be done by substituting a "." for symbols other than parentheses.
