Question
rank the subsequent 5 human-infecting viruses from 'Most disease-causing' to 'Least disease-causing' (i.e."1" being most disease causing, "5" least disease causing).**Explain Why Please**
-A virus containing genes that all have a promoter which is turned on only by human transcription factors that normally promote muscle growth.
-A virus with all outer epitopes similar to natural human epitopes.
-A virus that destroys all dendritic cells and can survive in airborne saliva particles.
-A virus that inserts DNA randomly into the genome but must insert its DNA specifically at the beginning of the host RNA polymerase gene in order to create new viral particles.
-A virus that cannot be bound by free antibodies but that, upon infecting cells, always presents a unique protein epitope on the infected-cell surface.
Explanation / Answer
4-A virus containing genes that all have a promoter which is turned on only by human transcription factors that normally promote muscle growth. This requires a specific transcription factor. 1-A virus with all outer epitopes similar to natural human epitopes. Only an autoimmunity disease would even attack this kind of virus, which means it goes without immune response. 3-A virus that destroys all dendritic cells and can survive in airborne saliva particles. Limited but not as limited as 4. 5-A virus that inserts DNA randomly into the genome but must insert its DNA specifically at the beginning of the host RNA polymerase gene in order to create new viral particles. Significantly difficult for a completely random insertion to insert in a specific location. Very low yields. 2-A virus that cannot be bound by free antibodies but that, upon infecting cells, always presents a unique protein epitope on the infected-cell surface. Many viruses are gotten rid of this way, because it takes less energy to destroy a whole cell than the x number of virus particles. It gets second most because it already causes the disease by the time a response is made.
