The Baltimore classification system is used to group viruses together based on their manner of messenger RNA (mRNA) synthesis and is often used alongside standard virus taxonomy, which is based on evolutionary history. DNA viruses constitute two Baltimore groups: Group I: double-stranded DNA viruses, and Group II: single-stranded DNA viruses. While Baltimore classification is chiefly … WebReplication of retroviruses. After a retrovirus enters a host cell, reverse transcriptase converts the retroviral RNA genome into double-stranded DNA.
