All prokaryotic and eukaryotic DNA polymerases share the same fundamental type of synthetic activity -an antiparallel synthesis from 5’ to 3’ from a template that is 3’ to 5’. This means adding nucleotides one at a time to a 3’–OH end.

#Unit 3. Fundamental Processes

The DNA polymerase monitors the ability of the incoming nucleotide to form an A:T or G:C base pair, rather than detecting the exact nucleotide that enters the active site in a DNA polymerase with significantly reduced discrimination
between dNTPs and rNTPs.
