Recombinant DNA
The advantage of using DNA polymerases from thermophilic organisms in PCR is that

the DNA polymerases of these bacteria can withstand the high temperatures needed to denature the DNA strands
the DNA polymerases of these bacteria are much faster than those from other organisms
the DNA polymerases of these bacteria never make mistakes while replicating DNA
All of these
