Figure 6.

Multiple sequence alignment of the deduced amino acids encoded by envelope gp41 gene of HIV-1 from mother-infant pair G after perinatal transmission. Each line refers to a clone identified by a clone number preceded by MG (for mother G sequences) and IG (for infant G sequences). The sequences of pair G are aligned to consensus B (cons B) on top. Dots indicate amino acid agreement with cons B, dashes represent gaps, and asterisks represent stop codons. The functional motifs of gp41 are indicated above the alignment.
