All DNA viruses … WebApr 13, 2024 · Like other viruses, HBV hijacks a cell’s molecular machinery in order to reproduce, but its process is a bit unusual. Once inside the nucleus, it uses that machinery to first transcribe its DNA to RNA, and then converts that into a new viral genome called covalently closed circular DNA (cccDNA).
