2008-02-01 17:50:37 by Michael in Medgadget
...RNA interference. Discovered just a decade ago, RNA interference likely evolved to help cells fight viruses. The cellular machinery involved in RNA interference first identifies short segments of suspicious-looking RNA, and then destroys all identical copies of that RNA. The result: None of the protein that the RNA encodes for gets made While...
