FIG. 7.

Schematic representation of the portion of U18-U19-U20 amplified by our PCR assay. The amplified DNA fragment is shown within the shaded area. The sequenced cDNAs of HHV-6A (U1102) and HHV-6B (CV) are indicated by thick lines, and the white line indicates the undetermined sequence. Spliced regions and their sizes are indicated. The size of exon D1/A2 is 170 bp. The locations of splice acceptor (A) and splice donor (D) sites are shown. The corresponding ORFs are shown. Full bars indicate stop codons, and small bars indicate start codons.
