Fig. 1From: A small stretch of poor codon usage at the beginning of dengue virus open reading frame may act as a translational checkpointRSCU values of each codon in the initiation sites of DENV1-4. The RSCU values of DENV1 (a), DENV2 (b), DENV3 (c), and DENV4 (d), as well as RSCUs of human highly-expressed genes are represented by the y-axis. The codon families for each amino acid are provided on the x-axis. Data in Additional file 3: Table S3 is presented as line graphsBack to article page
