Nucleotides of uracil are not required for DNA amplification, as DNA uses thymidine instead of uracil.
B. DNA polymerase.

The correct answer is DNA polymerase. This enzyme is essential for synthesizing new DNA strands during the polymerase chain reaction (PCR).
C. amino acids.

Amino acids are not necessary for DNA amplification; they are used for protein synthesis, not nucleic acid synthesis.
D. ribose sugar.

Ribose sugar is part of RNA nucleotides. In DNA amplification, deoxyribose is required, hence ribose sugar is not needed.
