Document Summary
Transition not entirely complete we still see rna being used as storage and a ribozyme. Life requires the ability to catalyze reactions that lead, directly or indirectly to the production of more molecules like themselves. Rna has the unique potential to act as both information carrier and catalyst. Assembly of rna polymers in the rna world is random. Function will depend on sequence = structure. Single stranded rna can fold into many different structures. Single stranded rna can fold into highly elaborate structures. Rna molecules which have specific biochemical properties isolated. These properties include catalyzing a variety of reactions. Main difference between protein enzymes and ribozymes is reaction speed not diversity of reactions. In the presence of the ligase, we see that it is able to take the substrate molecules and make larger dna molecules. In the presence of nuclease, it cleaves it to smaller dna molecules. An rna which can catalyze templated polymerization would be important.
