DNAzymes and ribozymes carrying 2'-C-methyl nucleotides.

DNAzymes and Ribozymes find applications as inhibitors of gene expression and in detection systems such as biosensors, among others. In particular, we are interested in the properties of hammerhead ribozymes carrying 2'-C-methylnucleotides and 10-23 DNAzymes containing (2'R) or (2'S)-...
