Sequence alignment of the recombination junctions of DpnI-resistant cccDNAs formed in cells transfected with HBV ΔDR, HBV Δr, HBV ΔYY, HBV M1, and HBV M2′. The 14, 9, 15, 13, or 14 junction clones of DpnI-resistant cccDNA obtained in HBV ΔDR-, HBV Δr-, HBV ΔYY, HBV M1-, or HBV M2′-transfected cells, respectively, were sequenced and aligned as described for Fig. 6.
