In an ideal polymerase chain reaction, one double-stranded DNA molecule is subjected to four complete cycles. Assuming complete duplication in every cycle, how many double-stranded DNA molecules will be present at the end?
- A.4
- B.8
- C.16Correct answer
- D.32
Solution
The DNA quantity doubles in each cycle. Therefore, after four cycles it is 2^4 = 16 molecules.
