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 ...

The more researchers examine RNA, the more surprises they continue to uncover. What have we learned about RNA structure and function so far? Although RNA is a single-stranded molecule, researchers ...

RNA splicing is a cellular process that is critical for gene expression. After genes are copied from DNA into messenger RNA, ...

RNA splicing is crucial for gene expression. After DNA is copied into messenger RNA (mRNA), noncoding parts called introns are removed, and the coding parts are spliced together.
