And what this basically allows that mRNA molecule to do is it prevents the mRNA molecule from being broken down and it also allows it to basically reach that final destination. And we'll discuss more about that in a future lecture. Now once we cap this end and once we add that tail the next process is the splicing process. 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.
