Dr Richard Hunt

Retroviruses have long terminal repeats in their proviral (DNA) form. What is an LTR? How are they different from the termini of the RNA form of the virus? Why do retroviruses have LTRs? What are the consequences of the possession of an LTR for the virus and the host cell? Please be concise and answer the question in no more than three pages

Dr Margaret Hunt

Viruses (including bacteriophage) frequently shut down host protein synthesis either directly or by decreasing the amount of host mRNA present. Discuss some of the mechanisms involved. Chose one of these mechanisms and suggest some experimental approaches you might use to investigate whether or not it is being used by a virus.
