Hepatitis B virus is the smallest DNA virus which is a member of the viral family Hepadnavirida. It uses its DNA as template and the RNA polymerase II of the host cells to transcribe its viral transcripts. There are four major RNAs transcribed from HBV genome. All of the four major transcripts are unspliced, terminated at a common site, polyadenylated at the 3' terminal and capped at the 5' terminal.
