WebGroup II introns are large, autocatalytic ribozymes that catalyze RNA splicing and retrotransposition. Splicing by group II introns plays a major role in the metabolism of … WebMar 11, 2002 · When cells produce a new protein, they first copy the appropriate gene into an RNA molecule. Next, the splicing machinery of the cell removes potentially harmful introns and welds together the so-called exons in the gene sequence. Many genetic defects are caused when splicing goes awry and too much is left in or out. ruth murton
