The proofreading function of dna polymerase reduces the error rate from about one in a million base pairs to about one in a __hundred million__ base pairs.

What is dna polymerase ?

All living things contain a particular type of enzymes called DNA polymerase. DNA replication and DNA repair and upkeep are two of its primary functions. The enzyme is essential for the generational transmission of genetic information.

  • In order to prevent translesion synthesis and to correct freshly created nucleotide incorporation mistakes from the primer terminus before further primer extension, DNA polymerases perform a process known as proofreading.

  • DNA polymerases' major function is to precisely and effectively replicate the genome in order to maintain the genetic information and ensure that it is faithfully passed down through the generations.
