Question

Dulbecco and Rubin discovered that they could infect chicken embryo fibroblasts with RSV in culture. Which of the following was NOT a characteristic exhibited by these cells after they were infected? O Virus particles were produced by these cells for many weeks. O Cells formed clusters, or foci, after infection. O The cells seemed to demonstrate uninhibited proliferation. O The cells exhibited flattened morphology. O The cells exhibited metabolic properties similar to those observed in tumor cells.

Answer 1

The cells exhibited metabolic properties similar to those observed in tumor cells.

Step-by-step explanation:

The cells infected with RSV did not exhibit metabolic properties similar to those observed in tumor cells. Rather, they exhibited flattened morphology and formed clusters or foci after infection, and they were able to produce virus particles for many weeks.
