Question

Are latent viruses more likely to be RNA or DNA viruses? How does converting the viral genome into episomes (circularized genome) or integration into the host chromosome help a virus?

Answer 1

Latency of the virus:-
   - latent virus are more likely to DNA virus.
- It is the ability of a virus to lie dormant within a cell.
- It denotes lysogenic part of the viral life

Advantages of episomes:-
     - It refers to the use of genetetic episome( circular DNA) during latency.
     -   viral genes are stabilized floating in the cytoplasm.
     -   Advantages is that the virus may not need to enter the nucleus, and may avoid from activating interferons.

- advantage of incorporation with host chromosome is that viaral DNA will automatically replicate with host DNA.
