A scientist discovers a new virus with a linear, RNA genome surrounded by a helical capsid. The virus is most likely a member of which family based on structure classification?
1. Rabies virus
2. Herpesviruses
3. Retroviruses
4. Influenza viruses
Solutions -
Genetic material can be linear or circular. It is linear and single stranded in viruses such as rabies, smallpox, retroviruses etc. Rabies virus has enveloped helical capsid.
