Concept explainers

Virus

Viruses are infectious microscopic agents that can only reproduce in live cells of animals, plants, or microbes and are smaller than bacteria. Vertebrates, invertebrates, plants, protists, and fungi are among their many hosts. Viruses are unable to multiply on their own due to the lack of necessary cellular machinery, but they can guide the cell machinery of a host to make additional viruses by infection. The virus enters and attaches to a particular host cell, injects its genetic material, and reproduces by using the host’s genetic material. Viruses cause infection by taking entry into the host cell and using the host cell’s enzymes and raw materials to multiply.

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. Rhinovirus
All virus particles, in their infectious form, contain which of the following components? Choose all that apply. Group of answer choices Ribosomes Mitochondria Nuclei Cell membranes Nucleic acids encoding genes Protein capsids
For 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 DNA
‘’Viruses cannot be grown in standard microbiological culture such as broth and agar. They need to be cultured in the presence of a suitable host such as prokaryotic cells (easiest to grow in the lab), plants and animals because they are unable to reproduce independently in living cells’’.2.2 What are the changes that are brought by a virus to a cell? In your response, make reference to the cytopathic effect (CPE).
A viral envelope performs many of the same physiological roles as the cell membrane of a cell such as enfocytosis or active transport. True or false. Explain Your answer.
TRUE or FALSE: All icosahedral viruses are enveloped. - Bacteriophages containing icosahedral heads attached to helical tails have this type of capsid structure: Modified Complex Icosahelical Helicosahedron
Which of the following statements accurately distinguishes between viruses, prokaryotic cells, and eukaryotic cells? Viruses are not cellular and require a host to replicate, prokaryotic cells lack a nucleus, and eukaryotic cells contain a nucleus and other membrane-bound organelles Viruses, prokaryotic cells, and eukaryotic cells all contain a nucleus Viruses and prokaryotic cells are always unicellular, while eukaryotic cells are always multicellular Viruses do not contain organelles, while prokaryotic and eukaryotic cells do
A viral mutation that causes changes in the glycoprotein spikes would affect which aspect of the virus? The virus would become lysogenic and incorporate its genome into the host cell genome. The virus would enter the host by a combination of endocytosis and fusion. The virus would lose its viral envelope and become a naked virus. The virus would attach to different host cells and its host range would be altered. The viral genome would not require uncoating once inside the host cell.
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.
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.
A viral envelope: is coded for in a viral genome is found within the capsid is not a true plasma membrane is part of some bacteriophages
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.
