Example Question #31 : Understanding Viruses And Prions

Successful reproduction of a lytic virus requires all of the following except which of these?

Possible Answers:

Incorporation of viral DNA into host DNA

Translation of viral DNA

Replication of the viral genome

Binding of the virus to the host cell

Entry of the virus into the host cell

Correct answer:

Incorporation of viral DNA into host DNA

Explanation:

A lytic virus does not require incorporation into the host cell's DNA. Instead, a lytic virus must attach to it's host cell and enter. Once the virus enters, it can take over the hosts' cellular proteins to replication. After replication, the copies will burst from the host cell and spread throughout the extracellular environment.
