NEET Zoology Genetic Engineering MCQ Question
What is the purpose of using a thermostable DNA polymerase in the process of DNA amplification?
It remains active during high temperatures for DNA denaturation.
It enhances the stability of the DNA fragment.
It increases the speed of DNA replication.
It prevents the degradation of DNA during storage.
Correct Answer
Detailed Explanation
A thermostable DNA polymerase, isolated from Thermus aquaticus, remains active during the high temperature induced denaturation of double-stranded DNA, which is essential for the repeated amplification of DNA segments.
