Retroviruses and Hepadnaviruses are both types of viruses that utilize reverse transcription in their replication processes. They possess single-stranded RNA (in the case of retroviruses) or partially double-stranded DNA (in the case of hepadnaviruses) as their genetic material. Both classes of viruses can integrate their genetic material into the host genome, leading to persistent infections. Additionally, they are associated with significant human diseases, such as HIV for retroviruses and hepatitis B for hepadnaviruses.
