The following table lists the 574 known families of non-coding RNA and other types of structural or regulatory RNA. We may very well want to change the names in the first column, to make them more explanatory for casual readers. :)
By clicking on the arrows in the top line of the Table, you can sort the whole table by the entries in that column; nifty, no? :)
