Fig. 7From: APA-Scan: detection and visualization of 3′-UTR alternative polyadenylation with RNA-seq and 3′-end-seq dataNucleotide composition of the sequence surrounding the polyadenylation sites identified by APA-Scanpeaks for MEFs samples. 50 bp up and downstream region is plotted with base sequences. x-axis denotes the position in the region, 0 is the location of the identified polyadenylation site. y-axis shows the fraction of the nucleotides content at each positionBack to article page
