Document Summary

Antigens: substances that stimulate antibody production by the immune system. 20. 1 the full extent of the diversity of bacteria and archaea is unknown could not learn much on prokaryotic organisms because they cannot be culturally grown (ex: required an extreme physiochemical conditions) Metagenomics: molecular techniques that developed to allow us to isolate and clone dna from an environment and then analyze gene sequences. Bacteria well on own to us through diseases and in the production of cheese, yogurt chocolate and etc. Archaea share some characteristics with eukaryotes and some with bacteria and some unique characteristics as well. Many of archaea live under extreme conditions that even other organisms including bacteria cannot survive. Prokaryotic organisms are smallest in the world and dominate life on earth. Their biomass exceeds that of animals and may be greater than all of the plant life. Prokaryotic organisms colonize every niche on earth and can also be found in.
