2. Content
•DNA viruses
•RNA viruses
•Comparison

3. DNA viruses
Contain DNA as genetic material
Large icosahedral and enveloped in lipoproteins
Some time referred as HHAPPY viruses because
 Herpes
 Hepadna
 Adeno
 Papova
 Parvo
 Pox

4. DNA viruses

5. RNA Virus
• Contain RNA as genetic material
• Mostly single stranded helical capsid symmetry
Toga
Corona
Retro
Picorna
Arena
Reo
Orthomyxo
Paramyxo

7. Comparison
DNA viruses RNA viruses
o DNA as genetic material o RNA as genetic material
o Mostly double stranded o They are single stranded
o Mutation rate is less than RNA viruses o Mutation rate is higher than DNA viruses
o DNA viruses are stable o RNA viruses are unstable
o Replicate in nucleus of host cell o Replicate in the cytoplasm of host cell
o Contain a large genome o Contain a small genome
o Newly synthesized DNA is packed in a pre-
formed capsid called procapsid
o Newly synthesized RNA is not packed in a
procapsid

8. Comparison
DNAviruses RNAviruses
o DNA viruses shows an accurate replication. o RNA viruses shows an error-prone
replication.
o Adenoviruses, Herpesviruses, Poxviruses,
Parvoviruses, and Hepadnaviruses are the
examples of DNA viruses.
o Reoviruses, Picornaviruses, Togaviruses, Ort
homyxoviruses, Rhabdoviruses, and
Retroviruses are the examples of RNA
viruses.
o Smallpox, herpes, and chickenpox are
diseases of DNA viruses.
o SARS, the common cold, influenza, hepatitis
C polio and measles are some of the diseases
caused by RNA viruses.
