Correct option:(A)Fragmentation of DNA
Solution:
- PCR is a technique used to amplify the DNA molecules present in a small sample in order to obtain a large amount of DNA sequence for the test.
- It followed by restriction fragment length polymorphism (RFLP).
- Enzyme restriction endonuclease is used for fragmentation of DNA.
- RFLP analysis is used to identify the repeated sequences by detecting a specific sequence pattern to the Variable Number Tandem Repeats.
- Which becomes that individual’s DNA profile.
- This is the basis of genetic fingerprinting.
