Viral Tagging

APBIO-NN4CJT

Bacteriophage viruses were produced in the presence of radioactively tagged materials, resulting in the presence of both radioactive proteins and radioactive nucleic acids in the viruses.

These viruses were then allowed to infect bacteria in normal growth medium. Viruses produced during the lytic cycle were sampled for radioactivity.

Which of the following parts of the virus should show radioactivity?

A

Neither the proteins nor the nucleic acids.

B

Only the proteins.

C

Only the nucleic acids.

D

Both the protein and the nucleic acids.
