Fig. 3From: 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 translational checkpoint of DENV1-4. The RSCU values of DENV1 (a), DENV2 (b), DENV3 (c), and DENV4 (d) are represented by the y-axis. The codon families for each amino acid are provided on the x-axisBack to article page
