How do viruses reproduce?
Attach
DNA or RNA
creating an immune response in the host
inserting DNA into the host cell
RNA mutates more frequently than DNA
bacteriophage
all of these
the virus had entered the lysogenic cycle
Vaccines can be used to prevent viral infection by:
Attach
DNA or RNA
creating an immune response in the host
inserting DNA into the host cell
RNA mutates more frequently than DNA
bacteriophage
all of these
the virus had entered the lysogenic cycle
Why do some viruses seem to go away and then return later, like a cold sore?
Attach
DNA or RNA
creating an immune response in the host
inserting DNA into the host cell
RNA mutates more frequently than DNA
bacteriophage
all of these
the virus had entered the lysogenic cycle
What is the first step in the lytic or lysogenic cycle?
