Question

DNA fingerprinting refers to

• A. molecular analysis of profiles of DNA samples
• B. analysis of DNA samples using imprinting device
• C. techniques used for molecular analysis of different specimens of DNA
• D. techniques used for identification of fingerprints of individuals

Answer 1

The correct option is C

techniques used for molecular analysis of different specimens of DNA

Important for DNA fingerprinting are short nucleotide repeats that vary in number from person to person but are inherited. These are Variable Number Tandem Repeats or VNTRs and these can be recognised only through molecular analysis of DNA samples. Alec Jeffreys (1985) discovered this technique for the first time.
