Hiv/aids a retrovirus that had a rna as dna so it made it possible to go from rna to dna. Panspermia a bacteria coming from the outside earth. If it (cid:272)a(cid:373)e fro(cid:373) earth its either fro(cid:373) rna or protei(cid:374), (cid:449)e do(cid:374)"t (cid:449)orry a(cid:271)out. Dna because we know it can be made from rna. Then use clays to figure out how nucleic acid codes for stuff. A molecule that has the ability to self-replicate. Carries the functionality to give orders that perform catalytic reactions, ribosomes synthesizing proteins. What we end up with rna world, rna molecule catalyzes the synthesis of a dna molecule (the storage molecule) Rna came first, containing the information for everything, giving the functions to proteins and storage to dna. Theres evidence that an rna can attach to a tertiary or quartenary structure.
