UPSC 2000: Assertion (A): “DNA Finger-printing” has become a powerful tool to establish paternity and identity of criminals in rape and assault cases. Reason (R): Trace evidences such as hairs, saliva and dried semen are adequate for DNA analysis.
(a)Both A and R are true, and R is the correct explanation of A
(b)Both A and R are true, but R is not a correct explanation of A
(c)A is true, but R is false
(d)A is false, but R is true
Attempt This Question
Not attemptedCorrect Answer: (a) Both A and R are true, and R is the correct explanation of A
DNA fingerprinting can uniquely match an individual’s genetic profile, so it is widely used in paternity disputes and forensic identification. Minute biological traces such as hair roots, saliva or dried semen contain sufficient DNA for analysis, and this fact directly explains the technique’s forensic power; hence both statements are true and R correctly explains A.
