Document Summary
Today we"re going to take a look at the interplay b/w rna and the organization of dna. Start first of all with the novel aspect of the regulation of rna done by organisms that invade eucaryotes & procaryotes & that"s viruses. Incidences of viral infection of animals such as the avian flu starting with fowl-like poultry but then migrating to humans. Such flu viruses can have profound impact on populations of individuals. Perhaps most profoundly in human population is the 1918 flu epidemic that killed 40 million people more than both world wars combined wiped out almost a whole generation of people sometimes called the spanish flu epidemic. Viruses don"t only infect animals but they infect everything from procaryotes to eucaryotes. Such bacteria that infect microbes are known as bacteriophage. There are others where we can see the exterior of the virus.
