The enzyme family of DNA polymerases plays a fundamental role in the replication, repair, and recombination of nucleic acid. Its members include DNA Polymerase b (Pol b), DNA Polymerase g (Pol g), and DNA Polymerase m (Pol m). TdT is a very unique and fascinating member of this family because, unlike all other DNA polymerases, TdT synthesizes DNA from only single-stranded DNA.
