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.
