Polyadenylation [poly (A)] signals (PAS) are a defining feature of eukaryotic protein-coding genes.

WebThe mature 3′-end in most pre-mRNA molecules is generated by cleavage at polyadenylation. For cleavage and polyadenylation reaction specific sequences are present in DNA and its pre-mRNA transcript which consists of 5′-AAUAAA-3′ that provides polyadenylation signal. It is followed by a 5′-YA-3′ and GU-rich sequence (Fig. 10.12).

Mature mRNA is the completely processed mRNA molecule in the cell of eukaryotes. The mRNA is a type of RNA involved in protein synthesis. It is synthesized based on a DNA template on the nucleus.
