Evolving new molecular function
First Claim
1. An in vitro method of inducing a reaction between first and second reactive units during a nucleic acid-templated chemical reaction, the method comprising the steps of:
- (a) providing (i) a template comprising a first reactive unit covalently attached to a first oligonucleotide comprising a codon and (ii) a transfer unit comprising a second reactive unit covalently associated with a second oligonucleotide comprising an anti-codon capable of annealing to said codon, wherein said codon or said anti-codon comprise first and second spaced apart regions; and
(b) annealing said first and second oligonucleotides thereby to bring said first reactive unit and said second reaction unit into reactive proximity and produce a reaction product that is not a nucleic acid, wherein, upon annealing, said codon or said anti-codon having said first and second spaced apart regions anneal to the corresponding anti-codon or codon via said first and second spaced apart regions to produce a loop of oligonucleotides disposed between said first and second spaced apart regions that are not annealed to the corresponding anti-codon or codon, wherein the loop of oligonucleotides permits the codon to anneal to the corresponding anti-codon and bring the first and second reactive units into reactive proximity.

Abstract
Nature evolves biological molecules such as proteins through iterated rounds of diversification, selection, and amplification. The power of Nature and the flexibility of organic synthesis are combined in nucleic acid-templated synthesis. The present invention provides a variety of template architectures for performing nucleic acid-templated synthesis, methods for increasing the selectivity of nucleic acid-templated reactions, methods for performing stereoselective nucleic acid-templated reactions, methods of selecting for reaction products resulting from nucleic acid-templated synthesis, and methods of identifying new chemical reactions based on nucleic acid-templated synthesis.

12. An in vitro method of inducing a reaction between first and second reactive units during a nucleic acid-templated chemical reaction, the method comprising the steps of:
-
(a) providing (i) a template comprising a first reactive unit covalently attached to a first oligonucleotide having a proximal end and a distal end and comprising a codon and (ii) a transfer unit comprising a second reactive unit associated with a second oligonucleotide comprising an anti-codon capable of annealing with said codon, wherein said first reactive unit is attached to an attachment site intermediate said proximal end and said distal end of said first oligonucleotide; and (b) annealing said oligonucleotides together thereby to bring said first reactive unit and said second reactive unit into reactive proximity and produce a reaction product that is not a nucleic acid. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
