The DNA synthesized would be most similar to Human DNA.
Explanation:
Polymerase is the enzyme that elongates the newly synthesized DNA strand on template strand by adding nucleotides.
The polymerase chain reaction uses a Taq polymerase i.e. polymerase from a thermophile bacteria called the Thermus aquaticus because it can remain functional at high temperatures..
The polymerase attaches itself to the template strand and adds complementary bases to the strand that is being synthesized.
Since in this case the template is a part of human genome, the new DNA synthesized will be similar to Human DNA.
