In the laboratory, morpholinos may be used to block translation or modify this process. EJC proteins are deposited about 20 nucleotides upstream of the site where it occurs, allowing errors in this process to be corrected via nonsense-mediated decay. In group I, guanosine acts as a cofactor for the first of two transesterification reactions, while in another version of this process, an adenine residue at the (*) branch point links to the 5-prime end of a cut mRNA segment, forming a characteristic loop called a lariat. This is facilitated by the action of several short uridine-rich compounds called snRNPs ("snurps"). It is self-catalyzed by ribozymes, and protein isoforms arise due to its alternative type. For 10 points, identify this process in which an mRNA transcript is modified by the removal of introns.
