NEET 2012 Biology question

PCR and Restriction Fragment Length Polymorphism are the methods for

(1)Genetic FingerprintingCorrect
(2)Study of enzymes
(3)Genetic transformation
(4)DNA sequencing

Answer: (1)

Solution

DNA (genetic) fingerprinting detects variations in repetitive DNA (VNTR) between individuals. The DNA is amplified by PCR and/or cut with restriction enzymes, and the resulting fragments, which differ in length from person to person
