Question :Assertion (A) : Synthetic oligonucleotide polymers are used during Annealing in a PCR. Reason (R): The primers bind to the double stranded DNA at their 1 complementary regions.

The correct answer is -The Assertion (A) and Reason (R) both are correct, and the Reason correctly explains the Assertion.

In PCR (polymerase chain reaction), synthetic oligonucleotide primers are used to initiate DNA replication. The primers are short, single-stranded DNA sequences that are designed to bind to the complementary regions of the target DNA sequence. During the annealing step of PCR, the temperature is lowered to allow the primers to bind to the single-stranded DNA template at their complementary regions. This allows the DNA polymerase to begin copying the DNA sequence.

Therefore, the Reason (R) correctly explains why synthetic oligonucleotide polymers are used during Annealing in PCR, and the Assertion (A) is correct.
