Abstract: A compound having the formula:
wherein, R1 represents 2′-O-R3-thio-R3 and/or 2′-C-R3-thio-R3, wherein R3 is a compound independently selected from a group consisting of alkyl, alkenyl, alkynyl, aryl, alkylaryl, carbocyclic aryl, heterocyclic aryl, amide and ester, X represents a base or H; Y represents a phosphorus-containing group; and R2 represents H, DMT or a phosphorus-containing group.
Abstract: Nucleic acid catalysts, method of screening/selection for nucleic acid catalysts, synthesis of ribozyme libraries and discovery of gene sequences involved in a biological process are described.

Abstract: A transcribed non-naturally occuring RNA molecule comprising a desired RNA molecule, wherein the 3' region of the RNA is able to base-pair with at least 8 bases at the 5' terminus of the same RNA molecule.
Abstract: Nucleozymes containing ribonucleotides and deoxyribonucleotides or nucleic acid analogues are described herein. The nucleozymes have catalytic activity and are significantly more resistant to degradation than their all-RNA ribozyme counterparts. Also described are methods for preparing the nucleozymes along with methods of using nucleozymes, e.g., as therapeutic agents.
