Document Summary
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. The property of rna molecules that allow it to be a catalyst for ribozymes is its ability to fold into shapes. Single stranded rna can hold into many different structure. >generate large pool of random dna and transcribe. >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. Random assembly of nucleotides is able to produce a functional ribozyme. An rna which can catalyze templated polymerization would be important. >make copies of itself, then make copies of other rnas, if neighbouring rnas have catalytic actions which are beneficial. A ribozyme which can polymerize 100% of its length.
