Name: RFAM - RNA families database of alignments and CMs Description: Rfam is a joint project involving researchers based at the Wellcome Trust Sanger Institute, Cambridge, UK and Janelia Farm, Ashburn, VA, USA. Rfam is a large collection of multiple sequence alignments and covariance models covering many common non-coding RNA families. For each family in Rfam you can:
* View and download multiple sequence alignments
* Read family annotation
* Examine species distribution of family members
* Follow links to otherdatabases
In conjunction with the INFERNAL software suite, Rfam can be used to annotate sequences (including complete genomes) for homologues to known non-coding RNAs. Please read important information about using Rfam for genome annotation. We provide pre-calculated lists of putative RNAs in over 200 complete genomes, and a web search facility for short sequences.
Rfam makes use of a large amount of available data, especially published multiple sequence alignments, and repackages these data in a single searchable and sustainable resource.

Name: NCBI Genbank Description: GenBank is a comprehensive database that contains publicly available DNA sequences for more than 205 000 named organisms, obtained primarily through submissions from individual laboratories and batch submissions from large-scale sequencing projects. Most submissions are made using the Webbased BankIt or standalone Sequin programs and accession numbers are assigned by GenBank staff upon receipt. Daily data exchange with the EMBL Data Library in Europe and the DNA Data Bank of Japan ensures worldwide coverage. GenBank is accessible through NCBI’s retrieval system, Entrez, which integrates data from the major DNA and protein sequence databases along with taxonomy, genome, mapping, protein structure and domain information, and the biomedical journal literature via PubMed. BLAST provides sequence similarity searches of GenBank and other sequence databases.
