In the Polymerase Chain Reaction (PCR), if 30 successive cycles are completed starting from a single duplex template, approximately how many DNA molecules are generated?

  1. \( 1 \times 10^6 \) (1 million)
  2. \( 1 \times 10^9 \) (1 billion)
  3. \( 1 \times 10^{12} \) (1 trillion)
  4. \( 30 \times 10^3 \)

Correct answer · Option 2

\( 1 \times 10^9 \) (1 billion)

Explanation

After 30 cycles, \( 2^{30} \approx 1.07 \times 10^9 \), which is approximately 1 billion times amplification.
