1. All Living Organisms are made up of 1 or more cells
2. The Cell is the fundamental unit of structure & function in all living organisms
3. All cells are essentially the same in chemical composition.

The Process

in the

Miller-Urey Experiment

1. 7 simple molecules (H₂0, N₂, NH₃, CO₂, CH₄ & H₂ (NO O₂)

2. Heat: to evaporate water

3. Radiation (Electric Discharge): provides NRG

4. Cooling System: Caputures molecules in liquid form for examination

The flow of genetic information from DNA (replication) to RNA(transcription) to Protein(translation).

1. Alanine
2. Asparic Acid
3. Glutamic Acid
4. Glycine
5. Urea
6. Lactic Acid
7. Acetic Acid
8. Formic Acid

With each round of heating, radiation and cooling, more complex organic molecules were formed.  These are:

1. Aldehydes
2. Simple Acids
3. More complex Acids including amino acids

1. Necessary for reproduction and evolution.
2. Present day: nulceic acid
3. Past: possibly RNA based

1. Some RNA molecules of enzymatic activity
2. RNA can catalyze the polymerization of nucleotides, including the synthesis of complementary RNA by using itself as a template. (not observed in DNA)

The ribozyme & the substrate may be 2 domains of the same RNA molecule.

Observed in:

• Genome replication in some RNA viruses
• Intron splicing

First, RNA based system 

Second, RNA & protein based system

Today, Central dogma
