- Can the below be added to the answer: Some common cytopathic effects include: Cell rounding and detachment: The infected cells may become rounded and detach from the underlying surface, leading to cell death and tissue damage. Cell lysis: In lytic infections, the virus utilizes the host cell's resources to produce new virus particles. As a result, the infected cell eventually bursts (lysis), releasing the newly formed viruses, which can go on to infect neighboring cells. Formation of inclusion bodies: Some viruses induce the formation of distinct structures called inclusion bodies within the infected cells. These inclusion bodies are often aggregates of viral proteins or nucleic acids and can be visualized under a microscope. Cell fusion: Certain viruses have the ability to cause infected cells to fuse together, forming multinucleated giant cells. This fusion enhances viral spread and can lead to the destruction of affected tissues. Cellular damage and functional impairment: Viral…TRUE or FALSE: Viruses undergo mitosis.TRUE/FALSEAll viruses are unable to resist the proteolytic activity (or digestive ordeal) once they are inside our cell organelles called proteasomes and lysosomes. True or False: The presence of at least one membrane is required for any organism to be considered alive.
- 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.Viral receptors are important to viruses because these will allow them to complete their replication inside the cell. True False‘’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).
- _____ mRNA is synthesized before replication of the viral nucleic acid.True or False: There are antibiotics that target viruses?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
- When a virus infects eukaryotic cells, one fate of the cell is lysis. List and briefly describe two other potential fates.A 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.During a lytic cycle, viral DNA replication occurs without phage production or the death of the cell while during the lysogenic cycle many copies of the phage are produced within the bacterial cell, the bacterium breaks open. Select one: True False
