How does the amount of target DNA generally change during each PCR cycle?

Answer and explanation

Correct answer: यह लगभग दोगुनी हो जाती है

PCR, or polymerase chain reaction, amplifies a selected DNA segment through repeated cycles of denaturation, primer annealing and extension. Ideally, each newly formed DNA molecule becomes a template in the next cycle, so the number of target copies approximately doubles per cycle. After n efficient cycles, the theoretical amount is close to 2^n times the starting amount, although real reactions eventually slow because of limiting reagents and other factors. Option A is correct. Halving, disappearance and conversion into stone do not describe DNA amplification.
