Rfam (http://rfam.sanger.ac.uk/)
Rfam is a collection of RNA sequence families,
represented by multiple sequence alignments and
covariance models (CMs).
The primary aim of Rfam is to annotate new
members of known RNA families on nucleotide
sequences, particularly complete genomes, using
sensitive BLAST filters in combination with CMs.
Rfam release 9.0 contains 603 families, each
represented by a multiple sequence alignment ofknown and predicted representative members of
the family, annotated with a consensus base-paired
secondary structure

Seed alignment for the U12 spliceosomal RNA family.
Secondary structure base pairs are encoded in the coloured bases in the
alignment,

An example of the new secondary markups used by Rfam. The coronavirus
30-UTR pseudo knot is shown (Rfam Accession RF00165sequence
conservation (A), covariation (B), base-pair conservation also known as thefraction of canonical base pairs (C) and CM scores (D).)

The tRNAdb, with one of the largest numbers of
entries among RNA databases, is not only an
excellent model system for implementing and
validating algorithms and processes of automated
nucleic acid data transfer, but also for thedevelopment of novel sequence analysis tools.
It also provides a basis for integration of structure-
function relationships and additional information on
evolution and phylogeny.

This is the most accurate tRNA gene databasecurated manually by experts in the world
This database is the outcome of the model projectto utilize the expertise of elderly researchers and topass it down to the next generation, which wascarried out at Nagahama Institute of Bio-Scienceand Technology. Specifically, the existing multiple
tRNA gene search programs are used for automaticsearch of tRNA gene from almost all sequencedprokaryote genomes, and then the expertsmanually check those cases in which different
results are generated by program.

RDP-II(Ribosomal Database Project)
http://rdp.cme.msu.edu/
The Ribosomal Database Project (RDP) providesribosome related data services to the scientificcommunity, including online data analysis, rRNA
derived phylogenetic trees, and aligned andannotated rRNA sequences.
The ribosomal RNA sequences in the RDP-IIalignments are mainly drawn from the majorsequence repositories(Gen Bank, EMBL Data
Library and DDBJ)According to RDP 10.28, it consists of 2,110,258
aligned and annotated 16S rRNA sequences.

siRNAdb (http://sirna.sbc.su.se/)
The siRNA database provides a gene-centric view
of human siRNA experimental data, including
siRNAs of known efficacy and siRNAs predicted to
be of high efficacy by siSearch
The database contains information about siRNA
molecules from two sources: (I) siRNAs collected
from the literature that have experimentally verified
efficacy and (ii) siRNAs selected computationally to
target the REFSEQ curated human gene set

(http://www-snorna.biotoul.fr/)
snoRNA-LBME-db is a collection of human small
nucleolar RNAs (snoRNAs) and Cajal body-specific
RNAs (scaRNAs), that serve to guide modifications
in rRNAs or snRNAs.
The database can be search by sno/scaRNA name
or Accession number, or by the position of the
modified nucleotide in rRNA/snRNA sequence.

(http://www.arb-silva.de/)
SILVA provides comprehensive, quality checked
and regularly updated datasets of aligned small
(16S/18S, SSU) and large subunit (23S/28S, LSU)
ribosomal RNA (rRNA) sequences for all three
domains of life (Bacteria, Archaea and Eukarya).
SILVA are the official databases of the software
package ARB.

This database is a comprehensive
mammalian noncoding RNA database
(RNAdb) containing sequences and
annotations for tens of thousands ofnoncoding RNAs.
These include a wide range of microRNAs,
small nucleolar RNAs and larger mRNA-like
ncRNAs. Some of these have documentedfunctions and/or expression patterns, but
the majority remains of unclear significance

The RNA modification database,
RNAMDB
http://rna-mdb.cas.albany.edu/RNAmods/
The RNA modification database provides a
comprehensive listing of post
transcriptionally modified nucleosides fromRNA .
The RNAMDB provides a user-friendly,
searchable interface that directs the user to
a detailed information page for each
