Origin of Life

Sequence the process of Abiogenesis

Abiotic synthesis of monomers → build macromolecules → make protocells (vesicle formed abiotically with properties of living cells) → self replication (ribozyme)

Abiotic Synthesis of Monomers Requirements

1. No oxygen

2. Source of energy

3. Inorganic building blocks/elements

4. Time

• Miller Urey experiment - found 26 Amino Acids

Macromolecules

• negative ions bond monomers

• clary/rock surfaces

Protocells

• Vesicle - form spontaneously from lipids in water

• Attributes of living cells

Self Replication

• Genetic information in DNA → RNA → Protein

Sequence the Major Events in the Evolution of Life

First Cells (anaerobic/heterotrophs) → Cyanobacteria (oxygen revolution/apocolypse, aerobic. autotrophs) → Eukaryotes (endosymbiosis - big cell eat small cell and becomes part of it)
