FIG. 1.

Alignment of HCV genotype 1 and 2 consensus nucleotide sequences with sequences obtained from two samples (601592 and 732829) with discrepant genotypes as determined by analysis of partial 5′NC and NS5B sequences. The nucleotide numbering is based on the HCV type 1 genome sequence (GenBank accession number M62321). *, same nucleotide at that position for all sequences; shaded box, phylogenetically informative position; R = A or G; M = A or C; W = A or T; S = G or C; K = G or T; Y = C or T; B = C, G, or T; D = A, C, or T; H = A, C, or T; V = A, C, or G; N = A, C, G, or T.
