Question

Consider there is only one double stranded DNA molecule initially along with all other requirements of PCR. If a PCR machines performs 10 cycles of reaction then bow many double stranded DNA molecules would be present at the end?

Options

• 82

• 164

• 1024

• 2048

Answer 1

1024

Explanation:

If only one double stranded DNA molecule was present at the start, the number of double stranded DNA molecules created at the conclusion of 'n' cycles = 2ⁿ = 2¹⁰ = 1024
