Question 1

latency

Answer 1

when virus co exist with their host cells, ensures virus can spread and replicate, no damage

Question 2

latency may lead to

Answer 2

genetic/phenotypic changes, exchange of genetic info

Answer 3

episome or integrates into cell

Question 4

provirus

Answer 4

euk virus, integrates in

Question 5

prophage

Answer 9

no

Question 10

clinical latency

Answer 14

important to placental development

Question 15

temperate phages

Answer 15

can enter latency

Question 16

why latency

Answer 16

Preserve sufficient host population to
ensure that the virus can continue to spread
and replicate
