Before delving deep into the subject, it is worth understanding a few crucial terminologies.
Messenger RNA – We are pretty much aware that RNA is used for a wide number of biological roles. These include expression of genes, coding and decoding of genes and also regulation of genes. However, the question that arises here is what makes these RNA so functional in nature? This is where the mRNA or the Messenger RNA comes into limelight. Using nitrogenous bases like guanine, adenine, cytosine and uracil, the cellular organisms puts messenger RNA into use to convey important genetic information of a being. The mRNA also facilitates the process of protein synthesis. In this case, the mRNA successfully gathers proteins on ribosome. Further, using procedures of transfer RNA, the molecules drop amino acids onto the ribosome. Ultimately, rRNA or the Ribosomal RNA links along-with the amino acids to create proteins or the building blocks.
RNA Sequencing – Popularly known as the Whole Transcriptome Shotgun Sequencing or the WTSS, RNA sequencing is a modern technology that puts the processes of next-generation sequencing into use to rack up evidences of RNA presence and their quantity in a genome in the form of snapshots. Performing RNA transcripts in a cell is quite a dynamic process. Other than expanding the nucleobase coverage of a DNA sequence, RNA-Seq transcripts can benefit multiple other functions like gene fusion, alternative gene spliced transcripts, mutations and post-transcriptional modifications. Living organisms when infected undergo varying cellular pathways. The RNA sequencing process maintains records of such changes and stores the information in the form of databases.Examples of RNA Databases: BPS – This database contain experimental information on RNA Base-pair structures.Recode – It is a database filled with information about translational recoding events, the RNA molecular weights and DNA conversions.Poly A_DB – All details about mammalian polyadenylation is stocked in the Poly A_DB database.RefSeq – This is a rich database containing references of 30,900 sequences.

Database of RNA-binding Protein Specificities
This University of Toronto site page provides a database of RNA-binding protein specificities where you can browse by domain such as RNA Recognition Motif, K Homology, CCCH Zinc Finger and more. Also you can browse by species such as Homo Sapiens, Mus Musculus, Drosophila Melanogaster and Caenorhabditis Elegans.
Noncoding RNA Database v2.0
lncRNAdb.org site has a searchable database which provides comprehensive annotations of eukaryotic long non-coding RNAs (lncRNAs). All entries are manually curated from referenced literature and each entry contains references information about the RNA including: Nucleotide sequences, Genomic context, Gene expression data derived from the Illumina Body Atlas, Structural information, Subcellular localization, Conservation, Function with referenced literature.
5S ribosomal RNA Database
The purpose of this database is to provide information on nucleotide sequences of 5S rRNAs and their genes. The sequences for particular organisms can be retrieved as single files using a taxonomic browser or in multiple sequence structural alignments.

This genomic tRNA database contains tRNA identifications made by the program tRNAscan-SE on complete or nearly complete genomes.
ncRNA
Noncoding RNAs Database.
Real Time PCR Primer Sets
Database of validated primer sets for quantitative PCR.
Ribosomal Database Project II
The Ribosomal Database Project (RDP) provides ribosome related data services to the scientific community, including online data analysis, rRNA derived phylogenetic trees, and aligned and annotated rRNA sequences.
RNABase
RNABase is an annotated database of all publicly available RNA structures.

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. They are synthesized by either RNA Polymerase I, II or III. The sequences reported here are based on actual sequence determinations and not on the basis of oligonucleotide catalogs.
The RNA Modification Database
The RNA modification database provides a comprehensive listing of post transcriptionally modified nucleosides from RNA.
The uRNA Database
The uRNADB is a tool in the study of the structures and functions of various U RNAs. It provides aligned, annotated and phylogenetically ordered sequences. The alignments of the sequences represent conserved secondary structure elements where each base pair is proven by comparative sequence analysis.
