What's the difference between mRNA and pre-mRNA? It's all about splicing of introns. See how one RNA sequence can exist in nearly 40,000 different forms. Next, the snRNPs U2 and U4/U6 appear to ...

Research into splicing mechanisms and patterns is essential for decerning fundamental biological principles, as well as clarifying the molecular basis of many diseases and developing new therapies. 2 ...
