Abstract:

Using complementary chimeric oligonucleotides containing deoxyribonucleotides and 2'-O-methylribonucleotides (1), enzymatically synthesized RNA (90 mer) were cleaved at a single site with Escherichia coli RNaseH, either at a hairpin loop or at a stem region. Especially, site-specific cleavage occurred in even the target region being enclosed within a stable, base-paired stem. The method is proved to be generally applicable to RNA containing secondary structures.
