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.
As a general rule, viruses are not considered to be alive based on several reasons. One such reason is that some viruses use RNA as their genetic material instead of DNA. Which of the five biological themes does this violate? Briefly explain why.
How common is ABV in the USA?
In the United States, over half of adults have been infected with ABV by age 40. Once ABV is in a person's body, it stays there for life and can reactivate.
Match terms with descriptions based on the text above. You can use an answer more than once or not at all.

- 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.arrow_forwardWhich 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.arrow_forwardThroughout history there are many different types of virus that have caused impacts both small and large. Is there a possibility a virus could be considered a "good virus"? Please provide an argument for both yes and no with the use of a proper example, facts and conceptual information.arrow_forward
- In electron micrographs of HSV infection, it can be seen that the intact virus initially reacts with cell-surface proteoglycans, then with specific receptors. This is later followed by viral capsids docking with nuclear pores. Afterward, the capsids go from being full to being "empty." Which of the following statements best fits these observations? The viral envelope is not required for infectivity, since the envelope does not enter the nucleus. The viral envelope mediates entry into the cell, the capsid mediates entry into the nuclear membrane, and the genome is all that enters the nucleus. Only the genetic material of the virus is involved in the cell's infectivity, and is injected into the host cell like the genome of a phage. Viral capsids are needed for the cell to become infected; since the full capsids enter the nucleus.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.
