DNA production during PCR can be calculated by the rule of 2ⁿ,where n equals the number of rounds of amplification.Approximately how many rounds of PCR are required to produce a billion DNA molecules from a single molecule,assuming that the PCR works perfectly? A) 10 B) 20 C) 30 D) 100 E) 1,000

Question

Quizplus · Accepted Answer

To produce a billion (10^9) DNA molecules from a single molecule, you need 2^n = 10^9. Solving for n gives n ≈ 30, since 2^30 is approximately 1.07 billion.
