Document Summary
The building blocks of macromolecules can be formed from nonliving matter if the conditions are right. Independently hypothesized that the atmosphere of the primitive earth was probably very different from today"s. This process of chemical evolution is called prebiotic evolution. The hypothesis of abiotic formation of organic molecules was tested in 1953 in the laboratory of stanley. Rich in hydrogen, methane, other hydrocarbons and ammonia. Most of these can come from volcanic sources. Easily form vesicle; needed to be next step closer to ______ Nucleotides prebiotic soup (of monomers) = increase in polymer formations. --condensation reactions are polymerization reactions in which the covalent linkage of the monomers is accompanied by the removal of a water molecule. All the building blocks can arise without life. >>>the building blocks accumulated and the simple molecules condensed into more complex ones. This might have taken place on the surface of minerals (clay) or in oily droplets floating in the.
