Identification of synonymous constraint elements in the protein-coding region of dengue serotype 2 quasispecies from next generation sequencing data
This study used bioinformatics tools to systematically identify synonymous constraint elements (SCEs) in the dengue serotype 2 quasispecies, which are signatures of probable overlapping functional elements in the viral genome. Sequencing data used in the analysis was generated using next generation...
