Document Summary

Large molecules composed of several connected subunits, that are identical or similar. Large organic polymers (proteins, nucleic acids and polysaccharides. ) Main question: can complex organic molecules be synthesized by simple molecules present in earth"s early atmosphere and ocean? (simulated earths early condition) Hypothesis: kinetic energy added to a mix of simple molecules with high energy then, rxns will occur that produce more complex molecules (ex. Result: solution contained many c containing, complex organic, and c-c bonded molecules (also contained lipids). To find exact products miller draw samples from apparatus at intervals found large quantities of hydrogen cyanide and formaldehyde (which lead to synthesis of more complex organic molecules. Significance: gives suggestion about monomers/building blocks involved in life. Environment: intense pressure, superheated water (up to 450 degrees), contains monomers. Thus, complex organic molecules could have been formed here. Meteorite in australia had building blocks on the outer layer (comes from places other than earth).
