In some genes the protein-coding sections of the DNA (“exons”) are interrupted by non-coding regions (“introns”). … This editing process is called splicing, which involves removing the introns, leaving only the yellow, protein-coding regions, called exons.

What is splicing in simple terms?

Listen to pronunciation. (SPLY-sing) The process by which introns, the noncoding regions of genes, are excised out of the primary messenger RNA transcript, and the exons (i.e., coding regions) are joined together to generate mature messenger RNA.

What is the splicing process?

RNA splicing is a process that removes the intervening, non-coding sequences of genes (introns) from pre-mRNA and joins the protein-coding sequences (exons) together in order to enable translation of mRNA into a protein. From: Handbook of Clinical Neurology, 2014.
