Verified step by step guidance

Understand the role of primers in PCR: Primers are short sequences of nucleotides that provide a starting point for DNA synthesis. They are essential for the polymerase chain reaction (PCR) because they define the region of DNA that will be amplified.

Recognize the function of DNA polymerase: DNA polymerase is the enzyme responsible for synthesizing new DNA strands. It requires a primer to begin the synthesis process, as it can only add nucleotides to an existing strand of DNA.

Identify the correct answer: The primary function of primers in PCR is to initiate the synthesis of a new DNA strand by providing a starting point for DNA polymerase. This is crucial for the amplification of specific DNA sequences during PCR.

Clarify misconceptions: Primers do not provide energy for the reaction, act as catalysts for peptide bond formation, or break hydrogen bonds between DNA strands. Their sole purpose is to serve as a starting point for DNA synthesis.

Summarize the importance of primers: Without primers, DNA polymerase cannot begin the synthesis of new DNA strands, making them indispensable for the PCR process. They ensure that the correct segment of DNA is amplified during the reaction.
