Which Enzyme Acts As A Proofreader During DNA Replication?

Which Enzyme Acts As A Proofreader During DNA Replication? DNA polymerases are the enzymes that build DNA in cells. During DNA replication (copying), most DNA polymerases can “check their work” with each base that they add. This process is called proofreading. What type of enzyme activity is required for DNA polymerase proofreading? Replicative DNA polymerases
