Complex Codon Usage Pattern and Compositional Features of Retroviruses

Computational and Mathematical Methods in Medicine, Volume 2013, Issue 1, 2013., 2013
Retroviruses infect a wide range of organisms including humans. Among them, HIV‐1, which causes AIDS, has now become a major threat for world health. Some of these viruses are also potential gene transfer vectors. In this study, the patterns of synonymous codon usage in retroviruses have been studied through multivariate statistical methods on ORFs ...
