In a typical PCR (Polymerase Chain Reaction) sample, four critical reagents are:

1. **DNA Template**: The sample containing the DNA that you want to amplify.
2. **Primers**: Short sequences of nucleotides that are complementary to the target DNA region, necessary for initiating the synthesis of new DNA strands.
3. **DNA Polymerase**: An enzyme that synthesizes new DNA strands by adding nucleotides to the growing DNA chain during the extension phase of PCR. A commonly used polymerase is Taq polymerase.
4. **Nucleotide Triphosphates (dNTPs)**: The building blocks of DNA (deoxyadenosine triphosphate, deoxycytidine triphosphate, deoxyguanosine triphosphate, and deoxycytidine triphosphate) that are incorporated into the new DNA strands during amplification.

These components work together to enable the amplification of specific DNA sequences in the PCR process.
