Which Is Not One of the Elements Needed to Amplify

Which is not one of the elements needed to amplify DNA by polymerase chain reaction (PCR) ?

A) Nucleoside triphosphates that serve as the source of the nucleotides A, T, C, and G needed in the synthesis of the new strands of DNA
B) A DNA polymerase enzyme that will catalyze the synthesis of a complementary strand of DNA from a template strand
C) The segment of DNA that must be copied
D) A restriction endonuclease enzyme that cleaves DNA at specific locations
E) Two primers-short polynucleotides that are complementary to the two ends of the segment to be amplified
