- what event occurs in bacteriophage multiplication that does not occur in animal virus replication?A,B,C,D, or E? a. adsorption to the host cells. b. injection of the viral nucleic acid into the host cell. c. host cell synthesis of viral enzymes and capsid proteins. d. assembly of nucleocapsids. e. replication of viral nucleic acid.arrow_forwardYou 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.arrow_forwardIf the HIV did not have a reverse transcriptase enzyme, then which of the following would apply? Select one: a. The virus can make use of the reverse transcriptase enzyme from the host cell to convert its RNA into DNA b. Viral particles will be produced without reverse transcriptase enzyme since the original HIV is an RNA virus and needs to assemble RNA ant coat proteins together c. The virus will manufacture its proteins from its RNA using translation and ribosomes from host cell d. Provirus will not be formed and assembly of viral particles will never occur e. The virus will not be able to recognise the host cell and therefore entry into the cell is blockedarrow_forward
- A positive-strand RNA virus: a.must first be converted to a mRNA before viralproteins can be translated b.is not recognized by host ribosomes. c.can directly translate viral proteins. d.will be degraded by host enzymes. e.needs RNA dependent RNA polymerase to get converted into mRNAarrow_forwardViral genomes can bea.

- Bacteria 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_forwardCoronaviruses have a positive-sense single stranded RNA genome. a.) What is the genome replication strategy of this category of viruses? b.) How do you think this feature affects the stability of the viral genome? (hint use figure below) Mutation rates in different types of viruses. Estimates obtained for viruses belonging to the major indicated groups are shown as a function of genome size. This reveals an effect of genetic material (RNA/DNA) and genome size on viral mutation rates.arrow_forwardThe table below shows the properties of the genomes of three different viruses. The data were obtained as follows: Nuclease sensitivity was measured by the ability of deoxyribonuclease (DNase) or ribonuclease (RNase) to destroy the genome (a “+" means sensitivity). The ability of the genome to act as mRNA was tested by incubating it in a cell-free system. If amino acids were incorporated into protein, the data are shown as a Finally, the virus particles were tested for the presence of a virion polymerase. If an enzyme was present, the data show whether it could polymerize deoxynucleotide triphosphates (DNTPS) or nucleoside triphosphates (NTPS). "+.

- Some retroviruses that have a wide host range have been developed for use in treatment of diseases or syndromes. These viruses do not result in a productive infection because they lack critical genes for viral replication, but they do carry DNA sequences that allow them to be packaged into infectious particles. Once in the host cell the viral DNA is released and integrates into the cell's genome. The advantage to this strategy is that the delivery of the DNA is very efficient. What is one possible problem of using a virus that can integrate into the human nuclear genome? Multiple Choice The virus carries genes that will interfere with host cell activities. The viral DNA sequences could still cause a disease. Since the viral DNA sequences no longer contain essential genes for viral replication the host cell may not be able to replicate either. The integration could disrupt an essential gene or genes.arrow_forwardThe dUTPase enzyme is used by the African swine fever virus to repair its own DNA, as the cells the virus infects in swine do not express the dUTPase protein. Which of the following is a reasonable explanation for the role of the dUTPase in the virus lifecycle? Explain your choice in 25 words or less. The dUTPase is necessary to remove dUTP from the viral genome, as uracil should not be present in DNA The dUTPase is necessary to remove dUTP from the viral genome, as uridine cannot correctly base pair with adenine-containing bases The dUTPase is necessary to remove dUTP from the viral genome, as uridine has the wrong sugar component for building DNA More than one of the above answers is correct None of the above answers is correctarrow_forwardWhich of the following statements are correct for RNA viruses?
