Answer:
The right words to fill the blank are DNA POLYMERASE ENZYME.
Explanation:
DNA polymerase chain is a method used in molecular biology to produce abundant copies of specific DNA segments. The process is catalyzed by an enzyme called DNA polymerase. The DNA polymerase enzyme is usually isolated from bacteria, which live in hot spring. One good example of such bacteria is Thermus aquaticus. The DNA polymerase isolated from this particular bacterium is usually preferred because it is heat stable and produce DNA strands at faster rates compared to natural DNA polymerase.
