DNA polymerases


DNA polymerases

Enzymes that bring about the synthesis of a daughter strand of DNA on the basis of a complementary DNA template. They are involved in DNA replication and repair, and act by adding deoxynucleotide triphosphates to the 3’-OH group of the new DNA strand. These enzymes not only synthesize new DNA but proof-read the new strand and remove incorrect nucleotides and replace them with the correct ones.
