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.

Splicing of pre-messenger RNA is regulated differently in the brain compared with other tissues. Recognition of aberrations in splicing events that are associated with neurological disease has ...

In multicellular organisms, the earliest products of transcription, called pre-mRNAs, undergo a molecular makeover before shipping out to the cytoplasm, where the modified mRNAs spell out the recipe ...

In human cells, only a small proportion of the information written in genes is used to produce proteins. How does the cell select this information? A large molecular machine called the spliceosome ...
