What is the most prominent sequence consensus for the polyadenylation site?
['the cannonical polyadenylation signal sequence AATAAA', 'Two AATAAA motifs are coded in the last exon of this gene', 'The results demonstrate that the intact AAUAAA is not required for RNA polyadenylation but is required for the cleavage step preceding polyadenylation to occur efficiently', 'the early poly(A) consensus signal was mutated from AAUAAA to UGUAAA', "Functional polyadenylation [poly(A)] sites consist of two sequence elements, the AAUAAA and G/U box signals, that closely flank the site of mRNA 3'-end formation", 'the appropriate spacing of the AAUAAA and G/U box signals is critical for poly(A) site function', ' Two AATAAA hexanucleotide sequences are present in the 2092 nucleotide interval. The first one functions as the major polyA signal']
