NEET Zoology Genetic Engineering Assertion Reason Question

Type: Assertion Reason-assertion-Hard-Class 12

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.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false but R is true.
