a, Structure of BDV N cDNA. The numbering corresponds to nucleotide positions in the BDV genome. The BDV N transcript runs from nucleotide positions 44 to 1193. b, c, Structures of BDV N integrations detected by Alu-PCR (b) and inverse PCR (c). Grey rectangles in the N cDNA indicate truncated regions. Black lettering, host genome sequences; green lettering, inserted nucleotides; red lettering, predicted TSDs. The blue box indicates the position and length of the poly-A sequence. The pre-integration form of chromosome 7 is shown in panel c.
