Fig. 2From: Does antiretroviral treatment change HIV-1 codon usage patterns in its genes: a preliminary bioinformatics studyPhylogenetic analysis using HIV-1 pol gene sequences isolated from treatment-experienced patients. Maximum likelihood trees (Bootstrap method with 1000 replicates) were constructed using MEGA6 (http://www.megasoftware.net/) [18]. HIV-1 pol gene sequences used in this study were found to be diverseBack to article page
