Give an example of a helical virus. Give an example of an isometric virus. You want to invent a new virus. While you are designing the basic genomic content, you need to consider controlling the release of progeny. The genome of MS2 phage is apparently too short to code for polymerase, adsorption protein, coat protein, and lysis protein.
Q b uses a different conservative mechanism.
Give an outline of RNA phage replication. Describe two important mechanisms of regulation of translation in RNA phage. Give an example of a virus which does this. In the case of polio, host translation is greatly reduced, if not halted entirely. Briefly outline, from translation to assembly, the making of a progeny polio virion.
