ou are helping a patient who you think has CJD. They want you to explain how this happened. Vhich explanation below is NOT correct? O spontaneous misfolding of the normal prion with age O possible transfer of abnormal prions on contaminated surgical instruments overuse of antibiotics O possible transfer of abnormal prions from blood transfusion

Retroviruses are dependent on reverse transcriptase, which does which of the following? Transcribes RNA backward (3' to 5' instead of 5' to 3') None of these are correct. Creates transcripts from an RNA template Creates a DNA copy of an RNA template.

Class V viruses carry their own polymerases within their viral particles: why is this necessary?

During infection of a cell by Coronavirus, the N protein is:     found on the outer surface of the virus particles     synthesized on bound ribosomes on the rough ER     synthesized in the cytosol on free ribosomes     part of the RNA-dependent RNA polymerase     required for binding of the virus particle to cells

Please help me with this question. More than one answer may be correct. The graph relating to the information is included below. The above graph is looking at the relative entry of SARS-CoV2 isolated spike proteins into human cells in culture at two times points: before introduction of the virus to the cell culture (0 minute) and 5 minutes after introduction of the virus to the cell culture. CHC stands for "clathrin heavy chain" and siRNA stands for small interfering RNA, which is often used in experiments as an easy method to stop expression of a certain gene. So in this case, the CHC siRNA would stop cellular production of CHC. The control siRNA introduces a small RNA fragment that does not match any gene as a negative control. Imagine that the experiment was then allowed to run for 500 minutes in addition to five minutes? How would the relative uptake of the spike protein into the control siRNA cells compare after 500 min to the 5 minute treatment? Options: 500 min time point would…

latent infection by animal viruses is most similar to which of the following events: lytic life cycle in bacteriophages O antigen shift antigen drift persistent infection by animal viruses O lysogenic life cycle in bacteriophages

Please answer with yes or no with correcting the falte statement. Felline to cottart the will cost the whole statements mark, 60) In case of human circovirus, in order to reduce mRNA for theit.D heel iD use two viral enzymies, one of them is the viral RNA dependent RNA polymerato they 61) In case of RNA viruses like orthomyxoviruses, the need to replicate in the nucleus in order to do the cep snatching. During replication the RNA polymerase will produce antigenomic copy in which this antiginomic copy will act as a template to produce the genomic RNA. The genomic RNA is the template for producing the proteins, and they are two raunds of transitions, in the firs round only fin polymerase is produced and in the second round only structure proteins are produced 62) In case of RNA viruses like Foot and mouth disuse virus, they need to replicate in the cyteplasm in order to produce RNA polymerase. During replication, the RNA polymerase will produce antigenomic copy in which this antigenomic…

of Poxviruses are unusual among DNA viruses because their replication cycles takes place entirely in the host cell cytoplasm. How can these viruses carry out genome replication and transcription of viral genes without going to the nucleus? Briefly explain.
