For proofreading in journalism or publishing, see Proofreading .
The term proofreading is used in genetics to refer to the error-correcting processes involved in DNA replication. In bacteria, all three DNA polymerases (I, II, and III) have the ability to proofread, using 3'->5' exonuclease activity. In eukaryotes only the polymerases that deal with the elongation (γ, δ and ε) have proofreading ability (3'->5' exonuclease activity).
