So essentially this splicosome moves onto our molecule. It removes these introns by essentially noticing specific sequences at the beginning of the introns. And by removing the introns it then basically connects these exons by forming the proper phosphor diastol linkages. And so eventually we form the following mature and fully functional mRNA molecule that now consists of only these coating regions that contain the codons that can be read by that particular ribosome and synthesize that polypeptide chain. Now notice that a common feature in the splicing process in the splicing mechanism is that the exons are actually ordered in the same sequential manner that the gene have those coding regions on the DNA molecule. So initially we begin with exxon number one, exa number two, exxon number three and what we see here is exxon number one, followed by exxon number two, followed by exxon number three.
