Chapter 5, Problem 18RQ
Many viruses enter host cells through receptor- mediated endocytosis, What is an advantage of this entry strategy?
- The virus directly enters the cytoplasm of the cell
- The virus is protected from recognition by white blood cells
- The virus only enters its target host cell type
- The virus can directly inject its genome into the cell’s nucleus.

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.
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
What allows the membrane of the HIV and the membrane of the host to fuse?
The virus capsid dissolves in the phospholipid bilayer of the host cell membrane
The virus contacts proteins on the cell membrane of the host, and then the viral
proteins undergo conformational changes
The virus docks at a pore, which then pulls the virus into the cell membrane due to
molecular attractions

- each virus bind to a specific cell surface receptor for attachment, so prevention of viral attachment how would you create a drug which will prevent viral attachment.arrow_forwardWhich 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.arrow_forwardAn 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_forward
- Which of the following highly contagious viruses is a single-stranded ribonucleic acid (RNA) virus with a helical capsid and envelope and is transmitted by coming in contact with respiratory secretions? "This is a highly contagious respiratory illness transmitted when an infected person coughs or sneezes virus particles into the air," the health department said in a written statement. "It's so contagious that if one person is sick and spreading measles, nine out of 10 people around them who aren't immune will get it, too." Group of answer choices a. Measles b. Parvovirus c. Coxsackie virus A d. Rhinovirusarrow_forwardWhich of the following statements is TRUE concerning viral envelopes? Only viruses with envelopes have their contents enclosed by a layer containing lipids Only viruses without envelopes interact with receptor proteins on the surface of the host cell. Only viruses without envelopes can release their genetic material into the cytoplasm of the host. Only viruses with envelopes package their genetic material by engulfing it.arrow_forwardA 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.arrow_forward

B lysosome (deacidified) С lysosome (acidified) B-coronavirus normal biosynthetic pathway egress via lysosomal trafficking SARS-CoV-2 inhibits lysosomes of its host cells by decreasing the pH within them. SARS-CoV-2 activates lysosomes of its host cells by decreasing the pH within them. SARS-CoV-2 activates lysosomes of its host cells by increasing the pH within them. D SARS-CoV-2 inhibits lysosomes of its host cells by increasing the pH within them.arrow_forwardFor a virus to transform a cell, which of the following events must occur: Group of answer choices Cytopathic effects must take place Virion production must be robust All answers are correct The cell must continue to divide The entire viral genome must always be integrated into host DNAarrow_forward

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_forward
