WebMay 1, 2002 · Enzymes that contain 3′–5′ exonuclease activities are involved directly in maintaining genome stability. They do this by removing mismatched, modified, fragmented and normal base-paired... WebDec 29, 2002 · The 3′→5′ exonuclease activity intrinsic to several DNA polymerases plays a primary role in genetic stability; it acts as a first line of defense in correcting DNA polymerase errors. A mismatched basepair at the primer terminus is the preferred substrate for the exonuclease activity over a correct basepair.
