RNA Activation
"More findings confirm that small RNAs work in mysterious ways. Nearly 20 years after its discovery, RNA interference (RNAi) is part of biology’s orthodoxy. Small RNA molecules can disrupt gene expression by degrading messenger RNAs (mRNAs) on their way to becoming proteins, or otherwise interfering with translation. But the discovery that these same small RNA molecules might be able to do just the opposite—enhance gene expression—was somewhat heretical". Full article @ The Scientist.com.
