The question is kind of confusing but from what I understand; missense mutations happen when an amino acid is changed to another amino acid. To find out more specifically, look at a codon chart trust me it helps so much lol (just search codon chart and go to images). missense mutations can also cause a premature stop codon so look for a changed amino acid and a stop codon when u look at the codon chart. maybe if u see the different pairs you can get a more specific answer. I hope this helps :)

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
