Most phages that use DNA to propagate work by hijacking host bacterial machinery including RNA Polymerase. Scientists found that treatment of jumbo bacteriophage PhiKZ with Rifampicin did not stop the phage from propagating. What is allowing for the survival of this phage?
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.

- 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.arrow_forwardIn Figure 5-2, in which of the four processes shown can acomplete bacterial genome be transferred from one cellto another?arrow_forwardIn which of the four processes shown can material from a bacterial genome be transferred from one cell to another?

- In some viruses the flow of information is in reverse that is ,from RNA to DNA.can you suggest a simple name to the process?arrow_forwardViruses are made up of the same biomolecules as cellular organisms (DNA, RNA, proteins, lipids, etc.). They infect cells and replicate themselves using resources from the host cells. Scientists discovered a previously unknown strain of virus in the tropical Pacific Ocean and it can infect higher-order eukaryotes. Initial analysis revealed that the virus is mainly composed of nucleic acids, proteins, and lipids. Chemical analysis after complete hydrolysis revealed the following building blocks (by weight): Chemical components Nucleosides Amino acids Lipids, phosphates, and carbohydrates Percentage by weight 20 30 50 Analysis of percentages of nucleosides yielded the following results (by molar ratio): Nucleosides A G T C U Percentage by mole 19 29 19 29 4 Researchers determined that the lipids found in the virus form a bilayer membrane surrounding the virus, and are obtained from the membrane of the host cell during virus maturation and exit from host cell.

It is a broad-spectrum antiviral, meaning it has activity against many different viruses. Remdesivir can be incorporated into a new RNA chain as a virus replicates and can interfere with the viral replication machinery. Template RNA Elongation New RNA SARS-CoV-2 RNA polymerase Template groove Nucleotide entrance Nucleotides Remdesivir Figure 1. A representation of remdesivir and the viral replication machinery for SARS-CoV-2. 6. Figure 1 shows that remdesivir "mimics” an important component of RNA replication.

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_forwardA plasmid may A) replicate independently of the chromosome.
