Why do most scientists agree that viruses are nonliving entities?

They cannot replicate outside host cells.

They are composed of relatively simple components.

They are not composed of cells.

They pass through filters.

They cause diseases in host cells.

Expert Solution

Option A;- CORRECT

Reason:-Viruses are obligate intracellular pathogens.They cannot replicate outside the host cell because they lack their own cellular machinery. It is an exclusive non-living characteristic of the virus.

Option B:-Incorrect

Reason:-Viruses are composed of simple components. The basic structure of the virus includes genetic material DNA/RNA. The genetic material is protected by a proteinous layer called a capsid. But this is not a non-living characteristic of virus.

Option C:-Incorrect

Reason;- Viruses are not made up of cells. They are made up of genetic material that is surrounded by a protective proteinous layer called a capsid.

Option D:- Incorrect

Reason: Viruses can pass-through filters as they are small in size. Even the bacteria like mycoplasma can pass through a filter. So it is not an exclusive non-living characteristic of viruses.

Option E:-Incorrect.

Reason:- Viruses are obligate intracellular parasites. This is not an exclusive non-living characteristic of virus.

How and where do many DNA viruses such as SV40 replicate in the host cell?

Scenario 2. Normally viruses infect a host cell, replicate themselves inside it and burst the host cell so that they can go on infecting other cells. In this viral infection, the virus has stopped the normal apoptotic pathway to allow themselves to stay within the cell indefinitely – a phenomenon known as latency. Further studies on this virus has shown that the virus encodes inhibitors of caspase 8 activation. Scenario 2 describes the development and maintenance of a latent viral...

Most RNA viruses are single stranded and replicate in the cytoplasm while most DNA viruses are double stranded and replicate in the nucleus. Briefly explain why this makes sense for each of these 4 characteritics (4 points). Each of the following viruses breaks one of these (e.g. might be double stranded RNA virus). For each of these viruses say which of these it breaks (4points). Bonus points. Describe the major pathology for Molluscipox virus and B19 Parvovirus (2points). Rotavirus, Molluscipox...

1- Cytotoxic T cells recognize and kill host cells infected by viruses. They recognize these cells by the foreign antigen displayed on the host cell’s: MHC I molecules MHCII molecules toll like receptors 2- Clonal selection: can be caused by vaccinations explains why the immune system responds stronger to a second infection than a first results in antibody specificity following a bacterial infection all of the above 3- Which of the following describes...
