Figure 2From: Functional relevance of nonsynonymous mutations in the HIV-1 tat gene within an epidemiologically-linked transmission cohortPhylogenetic analysis. Neighbour-joining phylogenetic reconstruction of tat clones based on nucleotide (A) and peptide (B) sequences. The differences in the tree topologies suggest nonsynonymous evolution of tat in each host. Donor A's clone A1-1 is underlined in both cladograms.Back to article page
