Question

Given below are two statements:
Statement (I): DNA fingerprinting technique involves identifying similarities in VNTRs.
Statement (II): The length of the regions having VNTRs is different in each individual.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

DNA fingerprinting depends on differences in repeat length between individuals, not on similarities.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept
VNTRs (variable number of tandem repeats) are repetitive DNA sequences whose number of repeats differs between individuals.

Step 2: Statement (I)
DNA fingerprinting identifies differences in VNTR patterns between individuals, so saying it identifies similarities is wrong. Statement (I) is incorrect.

Step 3: Statement (II)
Since the number of repeats varies, the length of the VNTR region is different in each individual. This gives a unique band pattern after hybridisation with a VNTR probe. Statement (II) is correct.

Step 4: Conclusion
Statement (I) is incorrect but Statement (II) is correct.

Final Answer:
Statement (I) is incorrect and Statement (II) is correct. \[ \boxed{\text{(D) }\text{Statement (I) is incorrect but Statement (II) is correct.}} \]
