Answer: A virus needs to attach to a living cell to get active. Viruses once entered the host cell it slowly damages it and finally destroy it. The virus replicate and produces biochemical and structural changes in the host cell. Viruses can harm many cells of the human body such as upper respiratory system. The HIV is the result of virus which enters in our body, replicates and weakens the immune system.
Many physician, scientist identifies the viral infection as by many of the ways to make sure that the infection is severe or not. Many of the viral diseases such as the Zika virus, nipa virus are the deadly diseases. We can only take preventive measures to ensure that the virus does not enter our body through any means. So we have to wash our hand frequently, should get flu shots, should always clean ourselves. We should stay hydrated.
The end result of most viral infections is death of the host cell. If this is...
Which viral replication doesn’t result in the death of a cell?
Which among A-D is false regarding most DNA virus infections and most non-retroviral RNA virus infections? A. Once inside the host cell, RNA virus replication usually (though not always) occurs completely in the cytoplasm. B. The genome of DNA viruses generally must enter the nucleus of the host cell they infect. C. A (+) sense RNA strand produced by an RNA virus could serve as an mRNA and be directly translated into protein. D. DNA viruses typically are assembled in...
Which statement among A-D is false regarding animal viral infections? A. Uncoating refers to the process of viral exit from the host cell. B. Depending on the virus type, assembly of viruses may occur in the nucleus or cytoplasm. C. Budding is a mechanism of virus exit that leads to acquisition of the envelope around the viral particles. D. Endosome formation is a mechanism that allows for the viral genome to be freed from the capsid. none of A-D are...
2. Gastrointestinal tract infections often result in cell death and shedding of intestinal epithelia. Sufferers are advised to consume only fluids initially, then simple foods such as the BRAT diet (bananas, rice, apple sauce and toast). Why?
Why can't viruses be grown on laboratory media? Most laboratory media is too rich for viral growth. O Viruses cannot be extracted from media without being damaged. Viruses require a host cell in order to replicate. Scientists haven't figured out what viruses need to grow. Trick question! Scientists grow viruses on media all the time
please answer all An example of a viral countermeasure occurs when Herpes and Pox viruses produce proteins that reproduce the activities of host proteins that regulate Cytotoxic T Cells Degradation of APOBEC Complement Activity Expression o MCH Class I Antigens Antibody Binding can result in neutralization of viral infection which may occur by Prevention of virion attachment to the cell receptors Antibody coated fusion proteins may inhibit fusion of the envelope and cell membrane Inhibition of genome uncoating Antibody Binding...
Please answer the last two bullets and the blank space in the second bullet. Pre Assemble, on their hosts' they metabolic machinery for replication, viruses are not considered living. A. Viral Infections Some viruses are merely nuisances while others can cause fatal infections. When a virus causes a worldwide epidemic, this is referred to as a punana An example of this would be: inFuuenza pandurni or vai8 While certain viruses can be prevented by vaccination, others cannot. In particular, that...
How do viruses acquire an envelope? Viruses manufacture cell membranes because it is encoded in their nucleic acid. Animal viruses don't make membranous envelopes; these are only produced in phage viruses. Only DNA viruses make envelopes because they have a gene for phospholipid production. When virus are released from host cell, they take the host cell membrane along with synthesized viral glycoproteins.
X-linked agammaglobulinemia in infants is most likely to result in excessive infections with this type of organism. A. encapsulated bacteria B. mycobacterium C. viral D. fungal E. parasitic worms
11) Why is it very difficult to fight viral infections? A) A virus is not alive and therefore impossible to kill. B) It is hard to destroy a virus without damaging the host. C) The cell wall of a virus is too thick to penetrate. D) A and B 12) A new class of antiviral agents called protease inhibitors has A) Prevent proteases from combining to form new viral agents B) Act as ion tunnels, inhibiting the ability of a...
