Question

The technique of DNA fingerprinting relies on _________.

• A. Repetitive DNA
• B. Minisatellite DNA
• C. Both A and B
• D. None of the above

Answer 1

The correct option is C Both A and B

DNA fingerprinting is based upon the fact that the DNA constitution of an individual carries some specific sequences of nucleotides that do not carry any information for protein synthesis. These specific sequences are repeated many times and found at many places within the genome. These loci are known as the Variable Number Tandem Repeats (VNTRs) or mini-satellites. VNTR belongs to a class of satellite DNA called mini-satellite.

So, the correct answer is option C.
