Table 3.
Usage of synonymous A‐ and G‐ending codons by the two references, KF383118 (A) and KU744693 (B). A codon set is defined as those triplets that share the same base and R (A/G) redundancy at their second and third codon positions, respectively. A summary of synonymous A‐ and G‐ending codon usage by all 56 ZIKV genomes (which is consistent with the trends for KF383118 and KU744693) is provided in Table S2
