1- Eukaryotic viruses often regulate gene expression throughactivities that alter the mRNA 5' cap or its recognition. Give anexample of such an activity and explain how it alters geneexpression.
2- How are T effector and T memory cells different and what aretheir roles in acquired immunity?
3- what are the similarities and differences between acute andsubclinical infections?
4- why does the adaptive immune system not immediately recognizeand clear herpes simplex virus-1 (HSV-1) when it reactivates (i.e.the latent cycle is broken and becomes lytic again)?
5-Do viruses with segmented genomes such as influenza usesequence-dependent or sequence-independent packaging? why?
6- You isolate mRNA from a virus-infected cell and sequence it.You find that there are many mRNAmolecules present and that theyare in different proportions relative to one another. The mostabundant mRNA is encoded at the 3' end of the parent RNA moleculean the least abundant mRNA is encoded at the 5' end. How was themRNA produced?
7- Explain how alternative splisingcan produce two mRNAs thatstart to encode in the "same frame" but end in an "alternativeframe"
