Question: 15
15. After infection of a cell, a viral particle must transport itself to the nucleus in order to produce viral proteins. What is the likely genomic content of the virus?
- A. Double-stranded DNA
- B. Double-stranded RNA
- C. Positive-sense RNA
- D. Negative-sense RNA
Correct Answer: A
Explanation:
A virus that requires transport to the nucleus in order to produce viral proteins likely requires use of nuclear RNA polymerase in order to create mRNA that can be translated to protein. Only DNA viruses require this transport before any protein can be synthesized.
