A nucleoside dimer in which the natural phosphodiester bond is replaced by an isosteric amide linkage has been prepared. This dimer analogue was subsequently incorporated chemically at the cleavage position of a hammerhead ribozyme substrate. Although the resulting substrate analogue

✦ Synopsis
The effects of the introduction of 2',5'-phosphodiester linkages within a hammerhead ribozyme domain have been examined in order to determine the regions which can be modified without impairing the cleavage activity and whether a substrate analogue, containing a 2',5'-linkage at the scissile position, could be cleaved.

We propose 2'-C-methylnucleotides as a new class of 2'-modified RNA mimics. These analogues are expected to provide 2'-OH groups capable of reproducing the interactions observed in natural RNA and, due to the presence of the Me group, to possess increased stability towards nucleases. In this work, w
