- 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. RhinovirusWhere do - ss RNA viruses assemble? O 1) golgi O 2) nucleus O3) cytoplasm O 4) both the nucleus and cytoplasm O 5) Endoplasmic reticulum Type:SSelect 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 components of a virus is NOT encoded by its own genome? O capsid of HIV O lipid bilayer of HIV envelope O spike glycoproteins of HIV envelope O anchoring structures of bacteriophageAll of the following statements correctly describes the properties of Influenza A virus EXCEPT A-Viral transcription occurs in the nucleus B-Mature virion are released by budding C-Single stranded positive sense RNA virus D-Attaches to cell-surface sialic acidHow 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.
- A viral particle adsorbs onto a host cell membrane. It uncoats and releases its single-stranded nonsegmented nucleic acid into the cytoplasm where it is immed dependent RNA polymerase, into mRNA. It is then translated into viral structural proteins and enzymes. Which of the following virus families is most likely repre A) Herpesviridae B) Paramyxoviridae C) Parvoviridae D) Reovirius E) RetroviridaeDescribe the lysogenic cycle of a virus.

- Coronaviridae is a virus “family.” There are actually many different coronaviruses within this group, including less pathogenic virus strains that cause the common cold. Many people in this course have likely been infected with one of these other coronaviruses. A common feature of coronaviruses and other RNA viruses (think influenza virus, HIV, etc.) is that they mutate frequently. This is because the viral enzymes that copy the genome during replication can’t fix mistakes. Given this information, how might we be able to distinguish the SARS-CoV-2 strain from some of the other, less concerning, coronavirus strains?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.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
