Document Summary

Anaerobic bacterial life, oxygen starts to accumulate (rust on bottom of oceans poisonous to bacteria) Formation of the solar system and planets ends with origin of life. Central dogma of biology: replication, transcription, translation. Dna rna(rna can be turned into dna because of the discovery of hiv aids called reverse transcription) protein. The rna world ribozymes rna is the compound that came first because it has catalytic abilities (catalyze and replicate themselves) Proteins first amino acid come first where they can self-catalyze and replicate themselves.
