WebIn most cases, the RNA is cut and spliced together by a spliceosome, a molecular machine composed of protein and RNA. In a few cases, however, the RNA can perform the splicing … WebAlternative splicing is now understood to be a common mechanism of gene regulation in eukaryotes; up to 70 percent of genes in humans are expressed as multiple proteins through alternative splicing. Figure 17.11 Before a RNA can be translated, introns must be removed by splicing. Pre-mRNA can be alternatively spliced to create different proteins.
