Example Question #31 : Understanding Viruses And Prions
Successful reproduction of a lytic virus requires all of the following except which of these?
Possible Answers:
Binding of the virus to the host cell
Incorporation of viral DNA into host DNA
Replication of the viral genome
Translation of viral DNA
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.
