Key result
RNA editing in HDV genotype III requires a branched double-hairpin structure involving the rearrangement of nearly 80 bp, which is essential for virion formation but not for RNA replication.

Establishes necessity of conserved RNA structure for HDV editing; leaves open whether disrupting ADAR activity offers antiviral strategies.
John Casey (2002) studied Hepatitis Delta Virus (HDV) genotype III. Branched double-hairpin RNA structure vs. Unbranched rod structure was evaluated on RNA editing and virion formation. RNA editing in HDV genotype III requires a branched double-hairpin structure involving the rearrangement of nearly 80 bp, which is essential for virion formation but not for RNA replication.
