Final answer:
HBV is a dsDNA incomplete virus belonging to the hepadnaviridae family. Most infected people develop chronic infection, especially infants. The virus uses reverse transcriptase to make its DNA genome.
Step-by-step explanation:
HBV is a dsDNA incomplete virus belonging to the hepadnaviridae family. It is transmitted by blood and blood derived products, including sexual route. Most people infected with HBV develop chronic infection, especially infants. HBV utilizes reverse transcriptase to make its DNA genome from pregenomic RNA. However, HBV does not use reverse transcriptase to convert its pregenomic RNA to dsDNA.
