The DNA polymerase enzymes has proofreading ability that makes it possible to correct wrongly paird bases either as the enzymes replicates or to correct at a later stage.

Because there is error checking in the enzyme systems involved in replication Pol 2 and pol 3 come to mind.

In complementary base pairing, Adenine (A) binds to Thymine (T) with 2 hydrogen bonds, on an identical time as Guanine (G) binds to Cytosine (C) with 3 hydrogen bonds. they continuously try this simply by fact of their length: length of A + T = length of G + C. this means that as quickly as DNA replicates, the bases that have been linked interior the 1st strand will bind to an identical base types as in the previous.
