Question

Assertion (A): For amplification of gene, DNA polymerase is used to copy the identified gene by polymerase chain reaction.

Reason (R): Amplification of a gene can be done by inserting it into a bacterium and allowing a bacterium to undergo repeated cell divisions.

पर्याय

• Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

• Both assertion (A) and reason (R) are true, but reason is not the correct explanation of assertion.

• Assertion (A) is true but reason (R) is false.

• Both assertion (A) and reason (R) are false.

Answer 1

Both assertion (A) and reason (R) are true, but reason is not the correct explanation of assertion.

Explanation:

DNA polymerase copies the target gene during PCR. Repeated bacterial cell divisions can also amplify a gene, but this is a separate method rather than an explanation of PCR.
