Textbook Question
Chapter 17.2, Problem 2CC
MAKE CONNECTIONS The RNA virus in Figure 17.7 has a viral RNA polymerase that functions in step 3 of the virus’s replicative cycle. Compare this with a cellular RNA polymerase In terms of template and overall function (see Figure 14.10).

Viruses with negative sense RNA genomes typically, make proteins by: (Ignore retroviruses, and the unusual characteristics of coronaviruses)
Translation of short RNA transcripts generated by RDRP
Generating a DNA copy, which is then transcribed by host RNA polymerase.
Translation of the viral genome by host ribosomes.
Production of a polyprotein, which must be cleaved into smaller proteins.
Generating a negative sense genome copy, which is then translated by host ribosomes.
You are studying a new retrovirus. The viral protein (X) appears to play a role in the export of the viral genomes to the
cytoplasm. Protein X brings viral DNA to the cytoplasm and returns back to the nucleus after genome export is complete.
Researchers have developed a new drug for the virus. Following treatment with the new drug, the viral protein stays in the
nucleus and cannot export the viral genomes. What is the most plausible and logical function of the drug? Use your
knowledge of nuclear transport to answer this question.
O A. The drug inhibits the binding of the viral protein and the viral genomes to the import receptor.
B. The drug inhibits the binding of Ran-GTP to the nuclear export receptor in nucleus.
C. The drug promotes the Ran GAP activity.
D. The drug blocks the NLS on the viral protein.
Assume you isolate a single stranded (+) RNA virus. When you examine the proteins in the virus, you find that it does NOT contain replicase enzymes within its capsid. Which of the following is true?
This virus must have a gene that encodes replicase.
This virus will not be able to enter a host cell.
Its genome cannot be translated (the process of translation) by the host cell ribosomes.
A DNA copy of the viral genome has to be made before viral genes are expressed.
This virus must lack surface antigens.

- Please answer fast You have been given the DNA sequence for a particular fragment of DNA. You then isolated the mRNA made from that DNA and amplified it by PCR. You then determined the sequence of the cDNA obtained from different cells. You notice a difference. In the sequence obtained from DNA sequencing you see that a codon is 5' CAG however on the cDNA sequence it is TAG. These results are confirmed by repeated DNA sequence analysis using DNA and cDNA from different cell cultures (same species and tissue samples). What can explain this? a.The DNA must have been mutated in all the cells that were used to isolate mRNA since the cDNA should always match the genomic sequence. b.Any cDNA made through RT-PCR will have T's substitued for genomic C's that are methyulated. c.The mRNA must have been deaminated at the cytosine. d.The cDNA generated most likely had a technical mistake caused by poor fidelity of the Taq enzyme.arrow_forwardLet's imagine you have discovered a new RNA virus and found a cell line to grow the viruses (lucky you!). Early experiments show virus' genome to be single-stranded RNA but you are unsure if it is positive or negative RNA. Explain how using anisomycin, an eukaryotic protein synthesis inhibitor, could potentially provide an answer.arrow_forwardFalsify and explain in detail why each choice is right or wrong (more than 3 sentences per choice) Regarding the influenza virus, which of the following is false? A. The viral mRNAs are translated on free ribosomes and bound ribosomes B. The viral envelope consists of host cell plasma membrane (phospholipid bilayer) embedded with viral glycoproteins. C. The viruses uses its own RNA-dependent RNA polymerase to synthesize an RNA molecule that is complementary to the RNA genome D.

- How are poly-adenosine tails added to subgenomic mRNAs of RNA viruses? Repeated uracil bases on the template cause the polymerase to slip backwards and recopy the sequence Polymerases copy a 200 base string of uracils found in some RNA viral genomes Polymerases copy a 200 base string of uracils added to the template during circularization Viral mRNAs undergo post-translational modifications, which include splicing of introns, a 5'-cap, and a 3'-poly-A tailarrow_forwardFigure 15.16 Many antibiotics inhibit bacterial protein synthesis.
