Figure 2From: Identification of candidate regulatory sequences in mammalian 3' UTRs by statistical analysis of oligonucleotide distributionsDistribution of strand-asymmetry z -values in 3' UTR and upstream regions. The distribution of the absolute value of z, defined in the text as a measure of strand asymmetry among all possible 7-mers in 3' UTR regions(red) and in 3000 bp upstream of the TSS (grey).Back to article page
