a Distribution of purine motif PTS across b pyrimidine motif of RefSeq genes and genomic features associated with RefSeq genes c mixed motif. The frequency of PTS was plotted for five distinct genomic features associated with the genes including 1000 bases upstream of TSS (promoter), 5′ Untranslated region (5′UTR), Protein-coding exon (CDS), Intron, 3′ Untranslated region (3′UTR) and 1000 bases downstream of transcription end site (1000 bp down)
