Document Summary

Precedes proterozoic eon and is preceded by hadean eon: begins 3. 8 billion years ago, anaerobic bacterial life, oxygen begins to accumulate. Biomonomer: the building blocks of biopolymers, used to form sugars, nucleic acids and polypeptides, creation of biomonomers in an experiment such as the miller experiment suggests that it would be possible for life to evolve from non-living matter. Polymers produced by living organisms: made up of biomonomers. Carbon: the basis of all life on earth, all organic molecules contain carbon as it is highly useful forming four bonds, extremely common. Proteins are responsible for the functional aspects of the living world: dna is self replicating, a protein cannot be used to create dna. Chemical evolution: a theory as to how life evolved on earth, life evolved on earth from non-living matter via chemical reactions, attempts to account for both metabolism and replication.
