VIROLOGY

      The study of viruses has historically provided and continues to provide the basis for much of our most fundamental understanding of modern biology, genetics, and medicine. Virology has had an impact on the study of biological macromolecules, processes of cellular gene expression, mechanisms for generating genetic diversity, processes involved in the control of cell growth and development, aspects of molecular evolution, the mechanism of disease and response of the host to it, and the spread of disease in populations.
     In essence, viruses are collections of genetic information directed toward one end: their own replication. They are the ultimate and prototypical example of "selfish genes." The viral genome contains the "blueprints" for virus replication enciphered in the genetic code, and must be decoded by the molecular machinery of the cell that it infects to gain this end. Viruses are, thus, obligate intracellular parasites dependent on the metabolic and genetic functions of living cells.
    Submicroscopic, different viruses range in size from smaller than the smallest organelle to just smaller than the simplest cells capable of energy metabolism and protein synthesis, the mycoplasma and simple unicellular algae. Despite their diminutive size, they have evolved and appropriated a means of propagation and replication that ensures their survival in free-living organisms that are between 10 and 10,000,000 times their size and genetic complexity.
