Dna Polymerase Reads The Dna Template Strand From The

Dna polymerase reads the dna template strand from the - The other function of dna polymerase 3 is proofreading the replicated dna. If it detects a mismatch, it can ‘snip out’ the wrong nucleotide and replace it with the right one. To avoid this, dna polymerase ‘proofreads’ the complementary strand as it moves along the dna. It is important that dna polymerase accurately copies the template strand to avoid placing the wrong dna nucleotide in the incorrect position. Hence, this enzyme reads the just added nucleotides, and if there is any mismatch with the template strand, it will be removed. The enzyme aids the base pairing of incoming nucleotides with the template strand. Dna polymerase 3 possess 3’ to 5’ exonuclease activity.
