Question

The technique developed to identify a person with the help of DNA restriction analysis is ______________.

• A. Cloning
• B. r-DNA technology
• C. restriction digestion
• D. DNA profiling

Hint:

DNA profiling is widely used in forensic science and paternity testing.

Answer 1

The Correct Option is D

Step 1: Understanding DNA-based identification.
Every individual has a unique DNA sequence except identical twins. This uniqueness can be used for identification.
Step 2: Role of restriction enzymes.
Restriction enzymes cut DNA at specific sites, producing fragments of varying lengths unique to each individual.
Step 3: Technique involved.
DNA profiling (also called DNA fingerprinting) analyzes these fragment patterns to identify individuals.
Step 4: Conclusion.
Thus, DNA profiling is the technique used for personal identification.
