Figure 1From: HIVBrainSeqDB: a database of annotated HIV envelope sequences from brain and other anatomical sitesSequence coverage of the HIV env gene, numbered according to HXB2. Start and end coordinates are represented, but sequences are not internally aligned so gaps are not represented. The x-axis shows HXB2 nucleotide numbering with a schematic of the env gene plotted above. The y-axis shows arbitrary numbering of the plotted sequences.Back to article page
