Solution
The correct option is A PCR
Conclusion
Polymerase chain reaction or PCR is a reaction carried out in vitro to amplify a specific DNA sequence or gene of interest and create its multiple copies.
- PCR is used in DNA fingerprinting only when the DNA isolated from the biological sample is in very small amounts.
- Thus, it is not mandatory to perform PCR in DNA fingerprinting.
Final answer: (a) PCR
