Question

Theoretical number of products formed after \(n\) cycles of PCR per template strand are

• A. \(2^{n}\)
• B. \(n^{10}\)
• C. \(n^{2}\)
• D. \(10^{n}\)

Hint:

Remember the PCR cycle sequence: \[ \boxed{\text{Denaturation} \rightarrow \text{Annealing} \rightarrow \text{Extension}} \] Each cycle ideally doubles the DNA amount. \[ \boxed{\text{DNA after }n\text{ cycles}=2^{n}} \] This exponential amplification is the basis of PCR technology.

Answer 1

The Correct Option is A
