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 ...
RNA splicing is a modification of the nascent pre-messenger RNA (pre-mRNA) transcript in which introns are removed and exons are joined prior to translation. For many eukaryotic introns ...
