How to assemble a living thing: accumulation of organic molecules, catalyze reactions, reproduce from stored genetic information, separate the living thing from the outside environment. Chicken or the egg: dna rna protein, need proteins to synthesize more dna, neither came first, how did earliest cells do it, ribozymes: i. ii. iii. Rna molecules that can catalyze reactions, especially those involved in synthesis and processing of rna itself. In conclusion: earliest cells used rna to store information. Order b. c. d. e. f. g. h.
