Figure 6

Alignment of the amino acid sequences. (A) V3 env region and (B) p17 gag region have been aligned, and a consensus sequence (top) has been generated. Question marks (?) have been introduced in the consensus when, in the specific position, no residue is found in more than 50% of sequences. Dots (.) indicate agreement with the consensus and dashes (-) indicate a gap inserted to maintain the alignment. Gray areas indicate perfectly conserved residues. Boxed residues indicate mutations possibly conferring resistance to class of drugs.
