Ensembl is a comprehensive database addressing the challenges of decoding a eukaryotic genome from the set of functional elements it represents in providing access to the vast sea of data [22]. Ensemble BioMart is a hub for data retrieval across the taxonomic space. We extracted 5 kb upstream of 109 and 180 genes involved in immune processes in sheep and goats, respectively from Ensemble BioMart. The sequences containing a string of undefined bases (N′s) due to partially complete contigs were eliminated for further analysis using a customized perl script.
