Which process is described in the following paragraph?
During DNA synthesis, before the enzyme adds the next nucleotide to a growing DNA strand, it checks whether the previously added nucleotide is correctly base-paired to the template strand. If so, the polymerase adds the next nucleotide; if not, the polymerase clips off the mispaired nucleotide and tries again. This is carried out by cleaving the phosphodiester backbone using the enzyme’s 3’-to-5’ exonuclease activity.
