Answer:
breakdown of DNA into small pieces
Step-by-step explanation:
- We use restriction enzymes to digest the DNA and break it into smaller fragments .
Steps in DNA fingerprinting:-
- Firstly we isolate the DNA .
- Breakdown of DNA using restriction endonucleases .
- Seperation of fragments by Agarose Gel electrophoresis
- Transferring this digested DNA into nitrocellulose membrane ( or any other synthetic membrane)
- Hybridisation using VNTR probe
- Detection of fragments by autoradiography.
