Which Of The Following Enzymes Has Proofreading Activity? 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. Which DNA polymerase has proofreading activity? In bacteria, all three DNA polymerases (I, II and
Which Subunit Is Responsible For Proofreading In Bacteria? The ε-subunit, which contains the proofreading exonuclease site within its N-terminal 185 residues, binds to α via a segment of 57 additional C-terminal residues, and also to θ, whose function is less well defined. The present study shows that θ greatly enhances the solubility of ε during
What Is One Reason That There Are Very Few Errors In DNA Replication? There are very few errors—only about one error per 1 billion nucleotides. Replication has a built-in “proofreading” process. If the wrong nucleotide gets added, DNA polymerase can find the error, remove the incorrect nucleotide, and replace it with the correct one. What
