Browsing by genome location
If you would like to examine ncRNAs found in a specific genomic location, you can use a lightweight genome browser that visualises RNAcentral sequences alongside genes and transcript from Ensembl and Ensembl Genomes (Figure 24). If you need more powerful tools, you can easily switch to Ensembl or UCSC genome browsers using the provided links:

RNAcentral has genome mapping for several important species, including human, mouse, fly, worm, yeast, and others.
Not every sequence in RNAcentral is mapped to a genome. For example, some sequences come from older genome assemblies and are not carried over to the latest assembly. Other sequences do not match the reference genome and may represent sequence variation. There is also a possibility of misannotation or contamination (for example, a bacterial sequence incorrectly annotated as coming from human), and such cases could be detected by checking Taxonomic distribution of a sequence or by running sequence similarity searches.
