Comments The terminal sequence of most mammalian genes contains the consensus AAUAAA hexamer (or a close variant). "Several studies on polyadenylation signal (PAS) suggested that while most human polyadenylation sites contain the canonical AAUAAA (70%), a large portion of genes have single-nucleotide variants, with AUUAAA as the most common one (16,19,20)."
