And therefore the three end tail that contains the many adenosine nucleotides is known as the polyadenosine tail or the polyadenine tail. Now, just as the five cap adds the ability to resist different types of degradation in the cytoplasm and gives our mRNA stability, the polyatail also provides the mRNA with stability and keeps the tail from degrading in the cytoplasm of the cell. And it also AIDS in the transport of our mRNA from the nucleus to the side of plasma of our cell. So basically what happens is if this is our mRNA molecule, if this is the premRNA molecule and this is the five end and this is the three end, what happens is a small section of the three end of the pre mRNA is cleaved, is removed and then we add a bunch of adenosine phosphates. How many? Well, anywhere from 200 to 250 adenosine molecules.
