Directions : In the following questions a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as :
Assertion (A) : A primer is a small segment of DNA that binds to a complementary strand of DNA.
Reason(R) : Primers are necessary to stop the functioning of DNA polymerase enzymes and, therefore, are necessary in polymerase chain reaction.
- a)Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).

Assertion (A) : A primer is a small segment of DNA that binds to a complementary strand of DNA.
Reason(R) : Primers are necessary to stop the functioning of DNA polymerase enzymes and, therefore, are necessary in polymerase chain reaction.
The correct answer is option D, which states that Assertion (A) is true, but Reason (R) is false.
Explanation:
A primer is a short segment of DNA or RNA that serves as a starting point for DNA synthesis. It binds to a specific region of the target DNA strand and allows DNA polymerase to initiate synthesis. The primer provides a free 3' OH group to which the DNA polymerase can add nucleotides.
Reason (R) states that primers are necessary to stop the functioning of DNA polymerase enzymes and are therefore necessary in polymerase chain reaction (PCR). However, this reason is incorrect.
PCR is a technique used to amplify a specific region of DNA. It involves a series of heating and cooling cycles that allow DNA synthesis to occur. Primers are essential components of PCR, but they do not stop the functioning of DNA polymerase enzymes. Instead, they guide the DNA polymerase to the specific region of DNA to be amplified.
During PCR, the reaction mixture contains the target DNA, DNA polymerase enzyme, nucleotides, and primers. The primers anneal to their complementary sequences on the target DNA, and the DNA polymerase extends the primers by adding nucleotides. This process is repeated through multiple cycles, resulting in the amplification of the target DNA.
Primers in PCR ensure the specificity of the amplification. They are designed to bind to unique regions of the target DNA, flanking the region of interest. By binding to these specific sites, the primers allow for the selective amplification of the desired DNA segment.
In summary, primers are small segments of DNA that bind to complementary strands of DNA. They are necessary in PCR to guide the DNA polymerase to the target DNA region. The reason provided in the question is incorrect as primers do not stop the functioning of DNA polymerase enzymes.
Reason(R) : Primers are necessary to stop the functioning of DNA polymerase enzymes and, therefore, are necessary in polymerase chain reaction.
The correct answer is option D, which states that Assertion (A) is true, but Reason (R) is false.
