Where can I find the DNA sequence of the C. elegans rRNA cluster?
Ideally, I would be able to do it using the command-line.
I have tried using the Bioconductor biomaRt package and create a table containing the description but when I grep 'rRNA', I only get proteins doing things with rRNA. I used the following code:
ensembl <- biomaRt::useMart('ensembl', dataset = 'celegans_gene_ensembl') wormGenes <- biomaRt::getBM(attributes = c('external_gene_name', 'chromosome_name', 'start_position', 'end_position', 'gene_biotype', 'description'), mart = ensembl) wormGenes[grep('rRNA', wormGenes$description), 6]  "rRNA 2'-O-methyltransferase fibrillarin [Source:UniProtKB/Swiss-Prot;Acc:Q22053]"  "Pre-rRNA-processing protein pro-1 [Source:UniProtKB/Swiss-Prot;Acc:Q22006]"  "Pre-rRNA-processing protein TSR1 homolog [Source:UniProtKB/Swiss-Prot;Acc:Q19329]"  "rRNA methyltransferase 2, mitochondrial [Source:UniProtKB/Swiss-Prot;Acc:O62251]"  "Probable rRNA-processing protein EBP2 homolog [Source:UniProtKB/Swiss-Prot;Acc:Q09958]"  "Putative rRNA methyltransferase [Source:UniProtKB/TrEMBL;Acc:Q5CCJ2]"
