The Baltimore classification groups viruses based on their genetic material and replication strategies, which is useful for understanding how viruses work. For example, dsDNA viruses, like Adenovirus 🦠, use the host’s machinery to replicate their DNA directly. But with RNA viruses, like HIV 🧬, the process is more complex—they reverse transcribe their RNA into DNA first, which is why we call them RNA reverse-transcribing viruses. This helps scientists target their weaknesses for better treatments 💊.
