Outline of the text: Origin of Life on Earth

 1- Origin of life studies

A- They Alexander Oparin and J.B.S Haldane identical hypotheses.

I- Formulate and test hypotheses about natural processes.

II-Formation of organic molecules the bullding Blocks of cells.

2-Miller-Urey experiments.

A-Reserch about the formation of organics molecules from inorganic compounds.

I- They Stanly Miller and Harold Urey tested the fiesta step of the Oparin-Haldene hypotheses by investigating for noción of organic molecules from inorganic comparads.

II-This simple apparatus causado chemical reactiona that produced a variety of organic molecules. 

3-Organic molecules from meteors.

A-Meteors that had some organic molecules when crashed the earth.

I- The Earth is bombarded with meteorites and dust from coments.

II- Scientis belive that such extra-terrestrual organic mattes contribuited sientifcantly to the organic molecules.

4- Enzymatic activity and hereditary information on one Polymer: the RNA World hypothesis.

A- RNA molecules can encode hereditary information and catalyze their own replicaron of polymers.

I- RNA molecules can catalyze their own site-especific.

II- RNA molecules, a single molecule or familiar or similar molecules could potentially store genética información and replicate.

5-Protocells: self-replicating and metabolic enormes in abrigo.

A- Cell hace lipid membranes that separate their inner contents from the environment. 

I-The allow cells to maintain higth concentración of molecules like nucleotides needed for self- replicaron RNA's.

II- RNAs function more efficiently.
