Question

Variable number of tandem repeats (VNTRs) in the DNA molecule are highly useful in which of the following?

• A. Recombinant DNA technology
• B. DNA fingerprinting
• C. Monoclonal antibody production
• D. Stemcell culture

Answer 1

The correct option is B DNA fingerprinting

DNA fingerprinting is the method of isolating, amplifying and imaging the DNA fragments to make a DNA profile. VNTR (Variable number of tandem repeats) are the region or segments in the DNA which contains the nucleotide repeats. These repeats are specific for every individual. These repeats are present in all the individuals but the number and the arrangement of the repeats are different for every individual. This forms the basis of the DNA fingerprinting technique to search for individuals on the basis of the VNTRs.

So, the correct answer is 'DNA fingerprinting'.
