A new mechanism of regulating RNA degradation
...scriptional regulation is called nonsense-mediated decay (NMD). Originally NMD was thought to destroy incorrectly transcribed or otherwise problematic RNAs, but investigators now know that it plays a major role in regulating the life span of numerous RNAs, and thus controls gene activity.
