This research demonstrates chemical reactions of RNA molecules that allow them to increase in length, from non-catalytic oligomers to complex RNA enzymes. The purpose of this research was to explain the origin of large RNA polymers required for life to begin in the proposed "RNA World". To do this, the Azoarcus group I ribozyme was engineered to catalyze phosphodiester exchange reactions that result in the recombination of short oligomer substrates marked by ^5'CAU^3' recognition tags.

To demonstrate the ability to produce catalytic RNA sequences through recombination, substrate oligomers were synthesized that could produce ribozymes if large portions of …
