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 ...

They can also be within the exon.” RBP splicing factors are sequence-specific, binding to their cognate sequence motifs like a lock and key. “Because the binding pocket of the RBP matches the sequence ...

Spliceosomes are large and dynamic RNA-protein complexes ... At least a dozen other steps are needed before the splicing reaction concludes. Not much is known about how the minor spliceosome ...
