Class 12 Biology Molecular Basis of Inhertance: NCERT Solutions for Question 13
What is DNA fingerprinting? Mention its application.
DNA fingerprinting is a technique used to identify and analyze the variations in various individuals at the level of DNA. It is based on variability and polymorphism in DNA sequences.
Application
(1) It is used in forensic science to identify potential crime suspects.
(2) It is used to establish paternity and family relationships.
(3) It is used to identify and protect the commercial varieties of crops and livestock.
(4) It is used to find out the evolutionary history of an organism and trace out the linkages between groups of various organisms.

Nice description and thank you so much
Nice note
DNA fingerprinting is a technique used to identify and analyze the variations in various individuals at the level of DNA. It is based on variability and polymorphism in DNA sequences. DNA Fingerprinting Techniques: 1) Restriction endonuclease analysis of chromosome (REAC) 2) Restriction endonuclease analysis of plasmid DNA (REAP) 3) Restriction fragment length polymorphism (RFLP) 4) PCR-RFLP 5) Random amplified polymorphic DNA (RAPD) 6) Direct amplification fingerprinting (DAF) 7) Repetitive sequence-based PCR (rep-PCR) 8) Pulsed field gel electrophoresis (PFGE) 9) Amplified fragment length polymorphism (AFLP) 10) Single-strand conformational polymorphism (PCRSSCP) 11) Multilocus sequence typing (MLST)
