Question

How many DNA copies are produced after five cycles of PCR (Polymerase Chain Reaction)?

Hint:

Each PCR cycle exponentially increases the number of DNA copies, making PCR a powerful technique for amplifying specific DNA sequences from small initial quantities.

Answer 1

Step 1: PCR amplification is an exponential process where the number of DNA copies doubles with each cycle. 
Step 2: The formula to calculate the number of copies after \( n \) cycles is: \[ \text{Number of copies} = 2^n \] 

Calculation: \[ 2^5 = 32 \] 

Conclusion: After five cycles of PCR, \( 2^5 = 32 \) DNA copies are produced.
