In addition to the basic structure of DNA polymerase, the Family A polymerases also has a 5'-3' exonuclease that is required for the removal of RNA primers from Okazaki fragments. Not all, but some Family A polymerases also a 3'-5' exonuclease that is responsible for proofreading the DNA.

The thumb, palm, and fingers subdomains are a part of the of N-terminal, or 31-kDA polymerase fragment in the Family X Polymerases. The palm in this family contains three aspartic acid motifs. The fingers in this family have Helices M and N that contain amino acid residues.
