NEET Zoology Genetic Engineering Assertion Reason Question
Assertion (A): Thermostable DNA polymerase is essential for the amplification of DNA during the PCR process. | Reason (R): Thermostable DNA polymerase is isolated from Thermus aquaticus, which allows it to remain active during high-temperature DNA denaturation.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The assertion and reason are both true, as PCR requires thermostable DNA polymerase to withstand high temperatures during DNA denaturation, and such polymerase is derived from Thermus aquaticus.
