Reverse transcriptase is needed to make DNA 
- Retroviruses are enveloped viruses with RNA genomes.
- After entering a host cell, the envelope and capsid disassemble and release viral RNA and proteins into the cytoplasm of the host cell.
- Then, viral reverse transcriptase converts viral RNA into doublestranded DNA (dsDNA) that is then transported into the nucleus.
- The enzyme integrase then facilitates the integration of the viral DNA into the host genome.
- Once integrated, viral DNA is replicated along with the host genome, and transcription and translation of viral DNA produce RNA and proteins that are assembled into new viruses.
