About the Small RNA Database Small RNAs are broadly defined as the RNAs not directly involved in protein synthesis. Small RNAs are usually in the 75-400 nucleotides range, although some are as long as thousand base pairs. The sequences reported here are based on actual sequence determinations and not on the basis of oligonucleotide catalogs. The references are restricted to the citation of the latest publication in those cases, where several papers deal with one sequence. In the case of capped small RNAs, the cap nucleotide is not included in the numbering system.
