Chemical modification patterns that are compatible with high potency 21-mer small interfering RNAs have been reported by several groups," scientists in the United States report.

"However, modification patterns have not been studied for Dicer-substrate duplexes. We therefore synthesized a series of chemically modified 27-mer DsiRNAs and correlated modification patterns with functional potency. Some modification patterns profoundly reduced function...
