Molecular evolution of hemagglutinin (H) gene in measles virus genotypes D3, D5, D9, and H1.
We studied the molecular evolution of H gene in four prevalent Asian genotypes (D3, D5, D9, and H1) of measles virus (MeV). We estimated the evolutionary time scale of the gene by the bayesian Markov Chain Monte Carlo (MCMC) method. In addition, we predicted the changes in structure of H protein due...
