Answer:
The correct answer is C dNTPs
Step-by-step explanation:
The deoxyribonucleotides which are added during PCR provides energy for synthesizing DNA strand .
The energy is generated by the breakdown of the terminal phosphate group or gamma phosphate group from the participating deoxyribonucleotides.
The hydrolysis of the terminal phosphate of deoxyribonucleotides generates energy for the joining of two adjacent nucleotides along DNA strand by phosphodiester bond formation. This result in the arrangement of deoxyribonucleotides along the two template DNA strands thereby helping to synthesize new DNA strand during PCR.
