Question

The Taq _______ enzyme is used in polymerase chain reaction (PCR) because it remainsstable at high temperatures.  A. DNA polymeraseB. RNA polymeraseC. ribosomal RNA (rRNA)D. ligaseE. nuclear

Answer 1

Explanation:

The polymerase chain reaction is a molecular technique used to amplify DNA sequences. The method uses short DNA sequences called primers to select the part of the genome to amplify.

Now, the heat-stability makes Taq DNA polymerase ideal for PCR. In fact, DNA polymerase is very heat-stable and is most active around 70°C.

Thus we can conclude that the correct answer is:

Answer:

DNA polymerase
