It explores various replication strategies of both DNA and RNA viruses, including double-stranded and single-stranded types. Key concepts like lysogeny and transduction are explained, along with the implications of latent infections, which can lead to conditions like cancer (e.g., certain HPV strains) or AIDS (via HIV-1).
