Localization of Duck Hepatitis B Virus Polymerase Within Cells

Hepadnaviruses are small, DNA-containing viruses that replicate by reverse transcription (1 ). They have a lipid envelope surrounding an icosahedral protein core particle, whose shell is composed of a single viral protein, the core protein. Within the core particle, the viral reverse transcriptase (polymerase) is covalently linked to the double-stranded viral genome.
