Why would viral genome integration into host cell integration be advantageous to a virus? It enables the virus to kill the cell. It allows the virus to infect cells it would not normally infect. It allows the virus to be passed on to future generations of host cells. It allows the virus to destroy the host cell's DNA. It speeds up viral replication

After a virus has entered its host, what factor usually determines the manner (or steps) in which the viral genome is copied and the viral enzymes are produced? the size of the virion the number of infecting virus particles the type of viral genome the type of viral capsid
How is the entry (penetration) of an animal virus into its host cell similar or different to the entry of a bacteriophage into its host cell? The entire viral particle (capsid and genome) can penetrate an animal cell, while only the viral genome can penetrate a bacterial cell. There is no difference; the entire viral particle (capsid and genome) penetrates both cell types. There is no difference; only the viral genome penetrates both cell types. The viral genome can penetrate an animal cell, while the entire viral particle (capsid and genome) penetrates a bacterial cell.
Which of the following is one way a virus can enter the host cell? Depending on the type of virus, each of the choices is a potential entry mechanisms. A virus can gain entry by fusing its membrane with the host cell's membe to transfer its genome into the host cell. A virus can gain entry by injecting its genome into the host cell. A virus can gain entry by fusing with the host cell's membrane so that the entire virus enters the host cell.
An antimicrobial drug binds to the HIV reverse transcriptase enzyme, preventing it from working. Which of the following is true of this drug? It would inhibit early replication steps of some viruses, but not affect normal eukaryotic cell activity. It would directly interfere with translation of some viral proteins and some eukaryotic proteins. It would block assembly/maturation steps of some viruses, and interfere with translation in eukaryotic cells. It would interfere with release of newly formed viruses from a host cell, but not affect eukaryotic cells. It would interfere with protein synthesis in bacteria, but not affect eukaryotic ribosomes. It would interfere with mRNA transcription in bacteria and viruses, but not affect eukaryotic transcription.
Which of the following is a similarity between viruses of bacteria (bacteriophages) and viruses of algae? These viruses will enter host cells by membrane fusion. They infect host cells by injecting nucleic acid (i.e., capsid does not enter cell) After replication in a host cell, the newly-assembled viruses will exit the cell by budding. These viruses are taken into host cells by phagocytosis.
The Ebola virus is an enveloped, helical ssRNA virus that replicates quickly. Given this information, which one of the following is a reason why Ebola infection is difficult to fight (both by our bodies and by treatments)? Question 6 options: Because it has many genes and thus replication is slow. Because it doesn't have a membrane. Because viral RNA polymerases make a lot of mistakes. Because it can integrate into the host cell DNA. Previous PageNext Page
A patient is admitted to the hospital with a viral infection and is immediately treated with broad-spectrum antibiotics. How will the course of the infection be affected by this treatment? The infection's length will remain the same because viruses do not have DNA or RNA, and so antibiotics do not affect them. The infection's length will be shorter because antibiotics can prevent viral entry into the cell by binding to host-receptor proteins. The infection's length will remain the same because antibiotics have no effect on eukaryotic cells or viruses. The infection's length will be shorter because antibiotics activate the immune system, and this decreases the severity of the infection.
All viral genomes contain nucleic acid, either DNA or RNA but not both. Viral replication is the formation of biological viruses during the infection process in the target host cell. Viruses must first enter the host cell before viral replication can occur. After gaining entry into a cell, the viral genome has to be first replicated using either the host DNA polymerase or RNA polymerase You are studying two viruses: Virus A is an enveloped RNA virus Virus B is non-enveloped DNA virus Which of the above viruses is likely to have the lowest mutation rate in the host cell? O Virus A because it uses the host RNA polymerase which has lower error rate than DNA polymerase. O Virus A because it uses the host DNA polymerase which has lower error rate than RNA polymerase. O Virus B because it uses the host DNA polymerase which has lower error rate than RNA polymerase. O Virus B because it uses the host RNA polymerase which has lower error rate than DNA polymerase.

The proteins on the surface of envelope viruses generally have to perform a few key tasks, including: (Choose all that apply) Translating viral proteins. Membrane fusion. Binding to molecules on the surface of host cells. Replicating the viral genome.
Viruses can carry out which of the processes described below? They can use the host cell to copy themselves and make viral proteins. They can use the host cell to copy themselves and then synthesize their own proteins inside the viral capsid. They can manufacture their own ATP, proteins, and nucleic acids. They can metabolize food and produce their own ATP.
Which of the following happens to the viral nucleic acid during a lysogenic cycle cycle? a-the viral DNA immediately takes over the host cell genetic material b-it bursts the host cell c-the viral DNA forms a provirus d-the viral DNA is used to attach the bacteriophage to the host cell`s receptors
