Goal of the virus is to find a host via its genetic info to make more copies by its host * Every type of organism has infected by a specific type of virus. **nanometer is one billionth of a meter. Most abundant organisms on the planet (biomass & # of species) Measured in micrometers (millionth of a meter) *30 trillion cells but at least 60 trillion bacteria cells. 3-4 lbs of bacteria (mostly in digestive tract) Can carry sm bc of size (small)
