Polymerase chain reaction namely PCR is a technique that amplifies DNA fragments rapidly in vitro. Generally, the process of PCR contains the following 30 times cycles: denaturation of template DNA at 95℃ → annealing (primer binds to DNA template) at 55℃ → extension to form the nascent DNA chain at 72℃. Which of the following statement is NOT true about PCR process:()

A. In PCR process, both of the two strands of DNA are synthesized continuously, the same as synthesis of leading strand in DNA replication.
B. The binding of primer with DNA template strand depends on the principle of complementary base pairing in melting process.
C. The process of extension requires DNA polymerase, ATP and four kinds of ribonucleotides
D. The optimal temperature of DNA polymerase in PCR process is higher compared with DNA replication in cells.
