RNAhybrid is a tool for predicting miRNA (microRNA) targets by calculating the minimum free energy of hybridization between target RNA and miRNA sequences.
The RNA Modification Database (RNAMDB) contains information pertaining to naturally occurring RNA modifications. The database employs an easy-to-use, searchable interface for obtaining detailed data on the 109 currently known RNA modifications. Each entry provides the chemical structure, common name and symbol, elemental composition and mass, CA registry numbers and index name, phylogenetic source, type of RNA species in which it is found, and references to the first reported structure determination and synthesis.
