Question 1
Plaque assays are used for
◦ evaluating the cancer-causing ability of a virus.
◦ counting the number of latent phages in a cell.
◦ cultivating viruses that cannot be grown any other way.
◦ the study of prions.
◦ determining the density of phage in a culture.
Question 2
Disadvantages of continuous cell cultures include
◦ the expense of preparation.
◦ they only grow for a limited number of generations.
◦ viruses do not reliably infect them.
◦ they may be significantly different genetically from the original source animal.
◦ they are both expensive and have a limited number of division.
