Document Summary

Formation of earth stable hydrosphere prebiotic chemistry pre-rna world rna world first dna/protein life last universal common. Miller-urey experiments showed that it was possible to synthesize basic molecules from the theorized environmental conditions of early earth. It was also proven that the four nucleobases could be formed. All the necessary components (sugar, nucelobases, phosphates) for the formation of rna are present and it is possible to obtain rna from early. Although it is possible, it is not proven. Clay may have played an important role in creating long strands of rna. Replicase catalyzes that synthesis of the complimentary strand: the additional activities that rna can perform is more evidence of an. Ribosome the cellular machinery that catalyzes the growth of a peptide chain: it is made of rna, reads rna, and synthesizes protein, provides evidence that the rna world came first.
