Abstract—The aim was to identify the factors affecting interaction[10], are accounting for the biased usage of
synonymous codon usage bias in the newly identified Duck Plague synonymous codons. In viruses, many literatures are recorded
Virus (DPV) gC gene, and parative analysis of the codon about the extent and origin of the synonymous codon bias.
usage bias in the gC-like genes of the 28 herpesviruses was Most retroviruses also exhibited a profound discrimination
performed by using CAI, CHIPS and CUSP program of EMBOSS. against the CpG dinucleotide sequence and the genome
The results showed that position, mutational bias bination characteristics strongly influences the codon
translation selection were the major determi
