Avirus cannot reproduce on its own. viral dna or rna must enter the host cell and direct the cell to make the materials needed to produce more viral particles. there are two pathways a virus may take: lytic or lysogenic. both pathways include five steps: attachment, penetration, replication and synthesis, assembly, and release.
one type of lysogenic virus is the herpes virus, which causes cold sores. how does a lysogenic virus differ from a typical lytic virus?
a) a lysogenic virus attaches and penetrates, but does not integrate into the host dna until conditions are favorable.
b) the lysogenic virus never instructs the host to produce new viral copies; instead it is replicated only through binary fission of the host cell.
c) the lysogenic virus, after penetration, immediately directs the host cell to replicate and synthesize proteins and then assemble new viral particles.
d) a lysogenic virus, after penetration, becomes part of the host cell dna, is replicated when the host divides, but does not not immediately replicate.
