Summary Introduction
Introduction:
Viruses are the organic entities that connect with living organisms, but they're not alive themselves. Viruses are regarded as non-living because they cannot maintain homeostasis and are unable to grow or reproduce without other organism's assistance.

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.
Select all the following statements that are TRUE regarding viruses:
□ All viruses are potentially dangerous to humans because any virus can infect any host.
□ Viruses are fastidious pathogens that require complex growth media.
□ Viruses are noncellular particles that take over the metabolism of a cell to generate more virus particles.
□ Viruses are genomes made of RNA and DNA that lack many protein.
□ Viruses can infect all other known life forms on earth, from Archaea to humans.
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.

- 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 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_forwardWhich one of the following is not true for virus, obligate intracellular parasites?

- Which of the following is a pyrimidine (one type of nitrogenous base) that is commonly found in all DNA molecules, but is not commonly found in all RNA molecules? adenosine cytidine thymine guanine uracil If retroviruses like HIV follow the historical pattern of a parasite adapting to a new host species (like syphilis in Europe over the past 500 years), then rapid virulence initially would likely be followed by: increasing virulence of the parasite, and decreasing resistance of the host increasing virulence of the parasite, and increasing resistance of the host decreasing virulence of the parasite, and decreasing resistance of the host decreasing virulence of the parasite, and increasing resistance of the host all of the above outcomes would be equally likelyarrow_forwardArrange the following list into the correct sequence for part of the cycle of a retrovirus: 1. dsDNA integrated into host DNA 2.viral proteins synthesized on host ribosomes 3. viral DNA uses host enzymes to transcribe viral RNA 4. reverse transcriptase catalyzes synthesis of ssDNA 5. synthesis of second DNA strand (a) 5, 2, 1, 3, 4 (b) 5, 2, 3, 4, 1 (c) 4, 5, 1, 3, 2 (d) 4, 1, 2, 3, 5 (e) 2, 1, 3, 4, 5arrow_forwardIf an animal virus does not lyse the host cell and does not produce symptoms, it is best described as morbid. chronic. latent. non-infectious.arrow_forward
