Tracing Pre-mRNA Processing from Transcription to a Mature mRNA
Captions available
The idea
This procedure traces a eukaryotic pre-mRNA from RNA polymerase II's transcription through capping, tailing, and splicing to a finished, translatable mRNA.
Where people slip
Capping, tailing, and splicing are three separate processing events, not stages of one single reaction — a pre-mRNA missing any one of the three is not yet a mature mRNA.
