Students have asked these similar questions
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.
Can u help me to explain to me, please?

- 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.arrow_forwardThe diversity of nucleic acids in plant viruses is great. Which class of viruses contain single-stranded RNA? These viruses are the source of which important enzyme (Hint: THis is the enzyme needed to make cDNA)?arrow_forwardO O O A new virus is discovered. Its RNA genome encodes several proteins, including a reverse transcriptase enzyme. What can you conclude about replication of this virus? Its replication involves a double-stranded RNA intermediate Its replication involves a DNA copy of its genome Its replication depends entirely on cellular enzymes Its replication is entirely independent of cellular enzymes 00 A deficiency in Base Excision Repair (BER) would primarily sensitize you to mutations caused by radiation, X-rays O Chemicals in smoke, and UV radiation O Unavoidable, spontaneously occurring DNA damagearrow_forward
- Discuss why viruses are considered nonliving.arrow_forwardThe DNA and RNA polymerases of viruses are typically more prone to making errors in the polymerization than are regular cellular polymerases. Why would be viruses be more tolerant of errors than are cells?arrow_forwardFor many years, scientist believed that proteins were the source of heritable information. There are many thousands of different proteins in a cell, and they mediate the cell’s metabolism, producing the traits and characteristics of a species. Researchers working with DNA viruses proved that it is DNA that stores and passes on genes. They worked with viruses with an outer coat of protein and a DNA strand inside. How did they prove that it was DNA, not protein, which is the primary source of heritable information?arrow_forward
- Viruses are host-specific, meaning they can only infect specific types of host organisms. For examble, the adenovirus is responsible for the common cold in humans but your dog can't catch a cold from you. Why is this? The proteins on the virus surface can only bind with proteins on the correct host surface. It is an enveloped or non-enveloped virus. The enzymes carried by the virus are compatible with the host. The genome of the virus is made of DNA or RNA.arrow_forwardIf a viral host cell has a mutation that interferes with the addition of carbohydrates to proteins (glycoproteins) during processing in the Golgi apparatus, which of the following processes is most likely to occur? O A. Viruses released by that host cell would have a decreased ability to infect cells than the virus that originally infected the cell. B. The virus-encoded protease would be unable to cleave large viral proteins into smaller, functional polypeptides. OC. The virus would be unable to replicate within the host cell. D. Viruses released by that cell are novel and would result in infections with higher mortality rates.arrow_forwardBacteria exposed to viruses incorporate sections of the virus’s DNA into the CRISPR array sequences in their genome. This mechanism allows bacteria to fight off the viruses, like an immune response: the information in CRISPR spacers served as “coordinates” for recognizing and cutting up invading DNA sequences. Describe what might happen under the conditions described after a bacteriophage infects a bacterial cell and releases its DNA into the bacterial cell. Explain why: 1. The invading phage DNA is recognized by the Cas proteins but not inserted into the CRISPR array region of the bacterial genome: The bacteria will be unable to elicit an immune response and will succumb to the phase infection 2. The cas genes on the bacterial genome contains a missense mutation that increases its cleavage/cut activityThe bacteria will elicit an immune response that will successfully fight the phage infectionarrow_forward
