The addition of a tail of polyadenylic acid (POLY A) to the 3' end of mRNA (RNA, MESSENGER).
Polyadenylation involves recognizing the processing site signal, (AAUAAA), and cleaving
of the mRNA to create a 3' OH terminal end to which poly A polymerase (POLYNUCLEOTIDE
ADENYLYLTRANSFERASE) adds 60-200 adenylate residues. The 3' end processing of some
messenger RNAs, such as histone mRNA, is carried out by a different process that does
not include the addition of poly A as described here
