FIG. 1.

HHV-6B and PCR primers. All exons (0 to 6) and introns are drawn to scale. The drawings of the mRNAs are in the same orientation relative to the HHV-6 genome. Thick arrows and boxes represent exons; introns are denoted by the lines connecting the exons. The locations of the PCR primers and a schematic drawing showing the use of the anchor primer RL-1 are also depicted. PSS, productive infection transcription start site.
