DNA production during PCR can be calculated by the rule of 2ⁿ, where n equals the number of rounds of amplification.About 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

According to the rule of 2ⁿ, for each round of PCR, the number of DNA molecules doubles. Therefore, we can calculate the number of rounds required as follows: 2^30 = 1,073,741,824 Therefore, it would take 30 rounds of PCR to produce a billion DNA molecules from a single molecule.
